I could not.
Be happier, the motor started up And had been running smooth ever since. I was happy that the motor was all painted cadillac blue. No oil leaks.. Thank.
You for a great job.Dan

- Dan - Nov 22, 2024

We purchased a remanufactured 2020 L83 5.3 AFM delete. Communication with customer service was superb. The instructions were clear enough, we documented everything they required replacing and then went beyond that just due to the mileage on the vehicle. Used HP Tuners to delete the AFM in the ECM. Just performed the required 500 mile oil change and its running great. Pictures show: 1) mated to the new 6L80e, 2) installed with the new water pump, vacuum pump, belts, tensioner, thermostat assy, new engine/transmission wiring harness, oil lines & trans lines. 3) close to done with new air filter.

Great company great products I get all my customers engines through promar . GET IT RIGHT AUTOMOTIVE appreciates you guys

- martell jones - Nov 20, 2024

This is the 3rd rebuilt engine (for three different Jeeps) we have purchased from them in the past 9 years. They have excellent quality and great customer service. We had two shipped to our home in Arizona, and the last one was shipped to a shop for us. The experience was smooth, and they communicated quickly. Our mechanic was impressed with their quality as well. While I hope not to need another engine anytime soon, I would buy from them again!

- S N - Nov 14, 2024

These guys are the ultimate professionals. They were on time with the delivery of my remanufactured 7.3 IDI. The engine has been on for two months now and it runs great, has awesome e oil pressure and power and does not use any oil. As an FYI. The engine is in an 18,000 pound roll back.

- Tony Esposito - Jul 10, 2024

Excellent job. To my specifications. Very good to work with.

- greg reisch - Jul 02, 2024

Great company! Bought an engine from them and love it!

- Nicholas Trousdale - May 01, 2024

As a 46 year GM dealership technician, I was a little hesitant about ordering a rebuilt northstar engine from anyone.
I'm truly impressed by the quality of their work, from the shipping process, including a well made crate, to the finished product running smoothly and quietly, knowing first hand the quirks of this engine for head gaskets and bolt thread issues. They did a great job, very pleased with their entire process

- Perry Pike - Mar 24, 2024

Promar was very helpful in answering any questions that I had concerning the remanufactured engine that I purchased from them. Can't wait for the install to be finished.

- Jeremiah - Mar 08, 2024

The motor seems to run great. Interaction with sales was ok but the engine was delivered with gaskets and some sheet metal I was not expecting so I had to return some of the parts I had purchased.
My only call to tech support was quickly answered.
Over all a great experience. just reached 1000 miles!

- david scardina - Mar 06, 2024

Great customer service. We received the engine we ordered in the time frame given. We had a bit of a delay getting the core back, but they worked with us. Overall, an excellent experience. Will definitely use them again!

- Kelly Powers - Oct 18, 2023

I received my 4.6 Northstar Engine in July of 2023. Unfortunately the installation into my 96 Eldorado was delayed due to illness. When I fully recovered the installation went well but I had to repair some electrical wiring gremlins that took some time to diagnose and repair.
I must say I was very happy to see the quality of the work on the Promar rebuilt Northstar Engine and the care taken to insure it arrived in beautiful condition . It is now running and purring quietly under the hood of my Eldorado. Thanks again for your patience and excellent product. A special tip of the hat to the fine technicians who rebuilt this engine!

- William Wilson - Sep 08, 2023

Very satisfied with the support and clear answers that was given to me. I will always recommend promar engines.

- Jose Reyna - Sep 05, 2023

5.4 3v. Ordered this engine for my 04 F150 Custom Truck. Had it Comp Cammed & Tuned straight out the box! So far so good. Engine thumps like none other!! Just completed my 500 mile oil change. No issues at this point. Breaking her in slowly. Engine is very responsive and performing well. Promar is a great company to do business with. They really worked with me on my core so that I didn't lose my warranty. Both Robin and Kevin assisted in the process. Great customer service! Communication is key. Promar is a name you can trust!!!

- Christopher Bradley - Sep 02, 2023

they were very helpful in remanufacturing my 5.0L marine engine. It came back in like new condition. It was done within the estimated time told.

- michael k - Aug 22, 2023

So far so good, all but the tacking on of added ship cost?

- Jessica Hazzard - Aug 15, 2023

Very courteous and quick to respond to questions and concerns. I would highly recommend their services. They stand strongly behind their products.

- Mark Pease - Aug 08, 2023

Very personable and informative. Top notch.

- cornell bell - May 27, 2023

- Joe Capolupo - May 03, 2023

I replaced the engine in my 1999 Ford F 150 lightning. The price was very good. My engine installer ran into a few problems but he worked it out with Promar. Car runs like new. Less than 1000 miles now so will get an oil change soon. Just a word of caution when installing a shortblock, you may be reusing your older parts on the installation and these may fail. Happened to me with the starter motor, but that was my own fault. Recommend you to use their services whole heartedly.

- Gene Lee - May 02, 2023

Delivery and core exchange went very smoothly and customer support was excellent.

- Richard Locarni - May 01, 2023

I can't say enough good things about these guys. They handled our engine concern quickly and efficiently. They kept me informed throughout every step of the process.
Our job was completed on time. The engine came back to us wrapped up in plastic and even included pictures of the various stages of progress.
I would recommend Promar to anyone. 5 stars!

- Cris Stellenwerf - Mar 02, 2023

After researching multiple vendors had Promar ship a long block 4 liter, 6 to Az for my 2000 Jeep TJ. Motor arrived ahead of schedule and after first 750 miles the motor purrs. Very pleased at this point. Shop that did the work impressed also...Thank You

- Terry Sims - Feb 19, 2023

Very well-built motor. I had one problem they address it immediately and corrected it immediately I would definitely recommend

I am extremely happy with the workmanship that Promar did on the motor rebuild even when I had a problem, they addressed it immediately and corrected it 100%. I would definitely recommend them.

- Christopher oliva - Jan 29, 2023

Runs great! Tks

- Highendauto Repair - Nov 25, 2022

Great Engine. Good warrantee

- mark bitner - Nov 22, 2022

Engine arrived on schedule and install was completed. Warranty paper work was sent and accepted. I look forward to the engine latest for miles.

- WDC LLC - Nov 22, 2022

Smooth transition. Motor arrived sooner than expected and the core was picked up the day after I called. 2500 miles so far and is running great.

- Dusty Tanner - Nov 19, 2022

My 2007 Daytona Charger had a blown engine since June 2021, so l had LONG time to research what avenue that I wanted to take.
Oct 2022 I decided to order from Promar and haven’t regretted my decision at all. Within a month, they asked for a review.
I chose to hold off until I got a couple thousand miles on her. Now l feel that l can give an honest review. After “break-in”, I’ve driven her like l stole her!
Absolutely a very sound engine with no problems and EXTREMELY strong. They answered all of my questions up front and were very helpful.
I wouldn’t hesitate to recommend or do business with them again.

- Pat McKeehan - Nov 11, 2022

I had an excellent experience working with Promar Engines. They were very helpful and went thru the entire process they use when rebuilding the engine for my 2013 5.0 F150. I opted to get all new valves because 11-13 model years had valve material issues and that was very reasonably priced. They used all new timing components but I wish I had specified they use oem Ford parts for that. My mistake, but so far no issues, but only time will tell if I have a phaser failure later on. I have 2000 miles on the new engine now and it is much stronger than the old worn out engine. My only complaint is it get 1 mpg less than the original. When I ordered the engine they said it would ship in 3-4 weeks. They totally exceeded that and had it out the door in exactly 2 weeks. For the installation I took it to my local Lincoln dealer as they only had 1 week lead time on appointments. I purchased all new sensors and water pump and associated components along with new plugs and coil packs, and new vct solenoids and various other parts to complete the engine build as Promar only supplies a long block. The dealer swapped out the engine by removing the entire cab of the truck. Then shipped out the core so that my warranty would be activated. You only have 30 days to return the core or your warranty will be void. That is a reasonable amount of time. Overall I'm very pleased with the experience.

- Jim Owens - Oct 09, 2022

Very good to deal with,quality products.

- jeanine sekel - Oct 07, 2022

Everything worked out great. I'm very happy with everything. Thanks guys great work.🙌🇺🇸

- Aaron Story - Oct 07, 2022

Engine arrived quicker than expected and is running great

- Tom Gilbert - Aug 15, 2022

Researching the engine was easy the promar people were good to talk to straightforward with us. Our 5.4 Ford V8 came quickly before it was expected. Looked super sweet visually clean and brand new like advertised. We have got it in our vehicle we have not yet ran the engine but I have no doubt it will be very Stout. Free shipping and free core return was a bonus. Will do business with promar again in the future when needed. Thanks promar for excellent service and product.

- Jeffrey Estabrook - Aug 11, 2022

Great Customer Service, even when engine got lost for a fee weeks. Have 1,000 miles on engine, no leaks, running just fine.

- Ed Lingenfelter - Jul 19, 2022

Had a great experience from the first time I called to the arrival of my long block. I ordered a Chevy 6L. LS2 motor for my 2005 SSR. I was told it would take about 4 weeks and it arrived on time with all the paperwork. I would definitely order again if needed for my next project.

- Art Keithley - Jul 18, 2022

It’s now been 3,000 miles on my new motor. I got 6.2/L99 from promar and I’m am truly happy. Followed the brake in period procedure before getting on it any. Went in to a G8 GT and had it tuned right and I am so Impressed, been running so heathy. Thanks again everyone at promar

- Matt Muskopf - Jul 12, 2022

Everyone at Promar Precision Engines were very friendly and helpful. My engine was delivered to my mechanic sooner than expected. The engine was just painted and looks fantastic. I cant wait to hear it purr once the project is finished.

- Nicholas C - Oct 13, 2021

great product for great price

- Frank Kish - Jul 25, 2021

I had the Promar team rebuild a 289 engine for our 65 Ford Fairlane. I have no clue on this stuff. My body shop took the engine out and I brought it down to Promar . The owner actually took me on a mini tour of the shop and what they do. Very, very interesting. Seemed like chaos to me--but they know exactly what they are doing. Kevin and team were super nice and answered all my questions. I was impressed as can be. They tell you what the cost will be on their website-- so very little to worry about.

- Kyle Maguire - Feb 18, 2021

Badass engine for a very reasonable price

- David Scott - Oct 21, 2020

perfect place for perfect engines

- LowGman - Oct 13, 2020

I ordered an AMC 4.2l motor and couldn't be happier. Uncrate, install, and drive. I shipped to a local UPS freight depot. Pickup and core return process was easy and pain free. It's made my 35 year old Jeep a dependable daily driver again.

- Justyn Plath - Sep 08, 2020

Smooth transaction and return of core. I am in California and both shipping and receiving went great. So far I have put 1000 miles on new engine and I dyno the engine and mild upgrades at 405 hp!! At 3500 rpm.. the engine and car runs like a champ now!!! My mechanic is a stock car racer and builds engines and he was impressed on the build quality.. I highly recommend!!

- Tristan Oreilly - Sep 08, 2020

Promar precision engines did a great job remanufacturing my 3.8L engine in my Jeep Wrangler. I was local so they picked it up, completed the work in about a week and a half, and return the engine to me ready to install. The guys at Promar Were very professional to work with, and couldn’t be more accommodating. I would definitely recommend Promar precision engines.

- G Hatalowich - Sep 08, 2020

There quality exceeded my expectations. Very easy to talk to there communication is extremely good. Very fast shipping. And so far the quality is good. I have put about 10 thousand miles on the7.3 idi. I bought from them and it runs perfect. I will be doing business with them if the future.

- Timmy Jolly - Jul 31, 2020

Engine shipped promptly. It went together with out issues and has been running great. Have put a little over 2000 miles on it now and I am very happy with my choice to go with Promar.

Great Job Guys

- Mark Beatty - Jul 24, 2020

Friendly customer service ,very professional,engine arrived within allotted time given,core return was not a hassle,engine has been running great,would recommend promar engines to all

- Harold Bess - Jul 22, 2020

It was my first.... my first diesel engine replacement. Was doing my research and found many positive reviews on Promar and their engines. So I took the leap and ordered a long block rebuild. Right now its in the truck or Moose as I like to call her, and she is purring like a kitten, but pulling like the moose she is. What a beast! I had some trouble with shipping (sat on dock for a week until I called Promar and they hunted it down). But all in all my experience with Promar was excellent. Everyone I spoke with was helpful. Thanks again Promar, and thanks for bringing Moose back to life....

- DurhamMill Lodge - Jul 22, 2020

- Milton Watts - Jul 15, 2020

My son needed a new engine for his 99 ford ranger. After researching a lot of different engine sites, we decided to go with Promar Precision. We are glad we did, the shipping was fast and the engine looked great also was a very reasonable price, it fired right up with no issues at all. Thanks Promar

- Jerry Siegismund - Jul 15, 2020

What a great engine! I bought one of Promar's upgraded Lightning engines and I've had no problems at all. I talked to the owner a couple of times about my wants and needs and he was always courteous and helpful. After those talks, I decided to buy an engine. It came right to my house. The packaging was amazing and once I got it in the truck, she started right up. No problems or leaks. I had more questions after the install and they helped me even more. If you need an engine, definitely give Promar a look!

- Jeremy Homrich - Jul 14, 2020

Hassle free. Reasonable price. Shipped directly to my installer. Fresh engine for my 200k mile 2004 F150. All in with a new trans and new everything under the hood costs about 6 months of new truck payments and insurance.

- Dan haynes - Jul 12, 2020

Promar gave me a great experience ordering !promar precision did a fantastic job on my AMC 360 engine for my Jeep grand Wagoneer.. they gave me a new oil pump where other companies offered a rebuild kit.. always answered the phone for my questions and thoughts.. free shipping especially on the return core. Some other companies want you to pay for the core that THEY want.. thank you Kevin and your whole team my motor runs perfect with oil pressure at 60 . Also is a great warranty .. just follow their guidelines and your set

- Dave Dye - Mar 18, 2020

So far, I am extremely satisfied with the whole experience! I took the car on a thousand mile trip after the break in period and could not be happier!
The engine I was looking for was available able to be shipped within a reasonable time to an exceptional shop, #AnthemAutomotive that did the install. The car I rebuilt is not your every day average ride and now I own one of the few '97 Cadillac Seville's left on the road because of #Promar! I can only hope and pray the engine and warranty is as great they tell me and lasts me another generation! Thanks!

- Bill Brough - Mar 02, 2020

5.4 ford 3v engine. Fairly priced, quick shipment, arrived timely and dressed as advertised, all needed gaskets included. Remain engine fired up without incident. Runs smooth and strong.

- Johnny Bass - Dec 30, 2019

Purchased a rebuilt engine for a 2002 Chevy s10 pickup I chose PPE because it was an owner operated company the communication was excellent and the motor runs like a fine Swiss Watch I would highly recommend this company

- Dave Serricchio - Dec 08, 2019

Customer service and support excellent. Kevin worked with me to provide exactly everything I was looking for- specific block numbers, fasteners etc beyond the basic build. Kevin continues to check in with me to be sure everything is going well.
My pair of long blocks were well packed & protected and made the long trip to Oahu with no issues or damage. All components are sound and well assembled and while I have not yet completed assembly and fired up the engines I have no reason for any concern.

- goodinmw - Dec 06, 2019

I was in search of a rebuilt engine for 2004 Ford F150, and I was concerned about buying a rebuilt engine from a company that I didn't know. I read their reviews and they looked good, so I went with Promar Engines. And that is why I decided to post a good review for them, because the other ones I read gave me confidence that I made a good choice. And so far everything has gone very well. The new engine seems to be running great. I liked that I did not have to pay a core fee, and the process to have new engine shipped and old engine picked up was pretty smooth. I appreciated the communication from the company, they were available to answer questions and quick to respond. Overall, very happy with the engine, the company, and the process. Would highly recommend to someone looking for an engine.

- Rich McClellan - Dec 05, 2019

Promar Precision Engines provided us with the best customer service and product. Our truck now sounds and runs like a brand new one. We are extremely satisfied and definitely recommend Promar Precision.

- Ron Broeder - Nov 28, 2019

Long block was at my local UPS Freight 24 hours after ordering. Came nicely packaged, with complete set of gaskets and break-in instructions, and labels with instructions for returning the core. Now have about 5,000 miles on the new engine, and my old Suburban runs like a new vehicle again. So pleased!

- J G - Nov 13, 2019

got a reman engine for my 07 JKU Wrangler and I couldnt be happier!

- Gretchen Rhodecap - Nov 13, 2019

High recommendation , great work, fast shipping

- Jay Gross - Nov 12, 2019

Product , fitment, and quality remanufacturing add up to a great value. They supplied every gasket required, detailed inspection instructions and made it incredibly easy to return original motor for core charge. Promar deserves the opportunity if you’re looking to replace an old or damaged engine.

- Jeremy Kelsch - Oct 26, 2019

Bought a 5.4 triton from you folks ,it just hit the 10,000 mile mark.Absolutely no issues and no ticking. thank god! Excellent job!

- Todd Clark - Oct 24, 2019

This company is the best most professional rebuilder I have ever used, always available on the phone, does exactly what they say. The engine was the best I have ever used, no issues at all after 2000 miles

- Joe the Computer Guy - Oct 15, 2019

I needed Promar to source the core for a 55 - 62 235 chevy, rebuild it and send it to me. It came in January and it took me until June to find all of the external parts I needed before I could install and get it started. All I can say is that it runs terrific and Mark and the other folks at Promar were terrific throughout the whole process.

- Mark Melander - Jun 30, 2019

got a jeep 3.8 remain engine from them. got a good deal on it. all worked good had no issue with anything. but had to reseal the timing cover after 1,500 miles. the gasket must of never sealed well. but wasn't any issue to me to fix. just didn't want to have to do to new engine that fast.
