I was looking for a 2019 Raptor Engine which I was initilly waiting for Ford to reman this engine. After the first deadline passed I realized Ford was not going to reman this engine. I started looking elsewhere. Almost every company wanted to sell me the engine Ford promotes as the replacement engine, which is the standard 350hp 3.5 liter engine that uses pistons with 10.5 to 1 compression ratio. Promar sold me a true Raptor engine with pistons preducing 10 to 1 compression which gived you 425hp. I was VERY impressed. Thank you, Kevin

Highly recommend great communication delivered on time as promised. Quality job one of the best I’ve ever seen. They gave me extra time on getting the core back with no problem. Great customer service.. Will be coming back this winter for my other motor. 454 merCruiser. Wish I would’ve found them three months earlier after I got screwed by another manufacturer.

ProMar Engine Rocks! My 2018 Chevy Tahoe LT 5.3L is now running on full V8 paired with Diablo Predator X. ProMar's AFM/DOD Delete is The One.

The motor was delivered in less time than I expected considering I ordered it between storms during late winter. The motor has been in for seven days and I already have 560 miles on it. It starts before 1/4 revolution and runs as smoothly as any factory motor I’ve ever heard. Thank you Promar for delivering a great product.

The motor was packaged well and the gaskets they sent were far better than expected. Once installed the motor started right up!! After I began the break in procedure I soon realized this motor was stronger than the original one! From my standpoint Promar builds a great engine!

Put a Promar 4.6 liter 2 valve engine in my 2001 Mustang rebuild. Was able to customize with a ProComp cam & polished headed. Promar engine runs great and car has more horsepower that the old engine. Further there prices were very reasonable.

After looking for someone to rebuild an engine for a 1985 Caddy with only 16K miles, no luck. No one will touch the HT 4100. This engine has a very bad history of running hot and warping the heads because of the 2 types of metal making up the engine. Most people hatted this engine, a few love it. But here I have a 1985 Caddy mint condition, car show perfection, but no engine. So long story short after nearly 1 year or first trying to get it rebuilt (no one would touch it), I started looking for other ways to get this gem back on the road, maybe a new engine. I had talked to a lot of people online and believe me they talk a good game, but they have no professional business savvy. (Don't trust these people), old saying if it sounds too good to be true then it usually is. No positive reviews and no BBB rating l So, I kept looking and here again no luck, until I came across the web site for Promar Engine remanufactured Engines. Now this company had hundreds of reviews, there is a picture of their business on the web site with phone #'s and a perfect BBB. rating. They go into detail on the way they manufacture all engines with pictures. I could go on and on, so if anyone reads this you can believe everything that I posted about this company. This company probably isn't the cheapest, but when you want quality and to deal with honest people, then this is the company for you. Visit the web site for Promar. All of your questions will be answered. If anything changes then reviews will follow, but really, I don't see it going that way.

Great experience with promar engine's! Got the new engine from them quicker than expected and looked perfect. After installing I ran through break in period and took it to tuner to double check everything was still on point. Runs great with 15lbs of boost and will deal with them in future if needed. I upgraded to forged crank and head studs for my needs

Purchased a Non-AFM 5.3 to replace a failed engine in my Silverado. Shipping was fast and affordable. The engine runs great. Have around 1000 miles on it after having it tuned by Michigan Motorsports and HP Tuners. Customer service and communication was very good, they kept me informed on parts orders, build completion, and shipping info. Highly recommend!!! Thanks Promar!!!

Great service and great product. I got my Gen2 Coyote long block from them a couple months ago, took my time building and installing, and just got my first start on it last night!

Outstanding Engine Rebuild – Like New Performance! Several months ago, I had Promar rebuild the engine for my 2012 Toyota Prius V, and I waited to write this review to truly assess the quality of their work. I can confidently say the results have exceeded my expectations. The rebuilt engine runs like brand new — smooth, quiet, and powerful. My fuel economy is back to 40 mpg, and I’ve had zero issues or strange noises since the rebuild. I’ve already done the first oil change, and everything remains flawless. Promar’s team was responsive, meticulous, and clearly committed to top-notch service throughout the process. Choosing to rebuild the engine through Promar was significantly more cost-effective than buying a new vehicle, and I couldn’t be happier with that decision. Highly recommend this company to anyone considering an engine rebuild!

This is my second engine from them customer service is outstanding truly ..You will not be disappointed..Went with a 426 stroker…..

I changed out the engine in my 2016 Ram pickup, it was a 5.7 litre Hemi with 261,000 miles for a Promar remanufactured long block and couldn't be happier, I've been commuting back and forth to work with it for 2 months now and hasn't given me any problems, Thanks Promar...

Everything went as planned. The engine shipped quickly and well packaged. The reman engine was clean as can be. Paint marked for torque settings. We saved the packaging for the core return. The new engine has a few hundred miles on it, and all is well. Old school Ford 7.3 IDI diesel.

Google

Everything was fine with the exception of the block threads for the headers. Several bolt holes were almost impossible to get a bolt to start. Long block arrived in a timely manner packaged very well. Was easy to set the core back in the crate and return.
