This motor is everything Steve and his company said it would be. I'm very happy with the build and turn key ready engine. Great customer service and integrity. Since this build in 2020 performance unlimited has built me an LS6 for my 67 camaro. Once build is completed I will share yet another awesome product.

Years ago, you built me a 461 Pontiac monster engine for my GTO. After I received it, the GTO went into a full resto-mod completed by Farland Classic Car Restoration in Denver. Took them nearly 4 years to finish it.

Your engine, and the GTO, are featured on Farland's website. If you click on this link, you can see their video and a slide show of the car and engine.

Or, you can just search for Farland Classic Cars in Denver, click on CARS, then on finished projects and scroll down to 1966 GTO.

Feel free to put the car/engine on your website under customer comments. Thanks for everything

From a very satisfied customer Michael C

Hello Steve, this is Gino from Canada. The 289 engine you did for me in installed in this 12971 Datsun 240Z .
Thanks for all the support and a great engine. If ever I get a chance I may drive down and shake your hand.

I would like to say you are the best so forget all the rest, and because I have bought 2 motors from you and always the same people work there. I can call and get answers any time and Steve gets right back to me with the most stupidest questions I have so always remember they have THE BEST motors and service around. Thanks Jerry S

Years ago, you built a crate engine for my GTO. I took your engine and my car to a place called Farland Classic Car Restoration in Denver Colorado. Now, 3 years late, they have finished my GTO with your beautiful engine cradled inside.
When I bought your engine, Steve asked I send you pictures of the final job. If you click on this link, it will take you to Farland and the show they have on the car, just delivered. Check out your engine! https://farlandcars.com/cars/1966-pontiac-gto-red

Hello Steve, Doug and Team

Thank you so much for the wonderful build of my Ford 408 Stroker motor. I bought this 1965 Mustang fastback at age 19 just before I went into the Navy. I traded a 1965 Mustang notchback (my first car), a dirt bike, and 900 dollars for it. It was wearing Shelby clothes when I got it but it is not a Shelby. I drove it for a while and then put it in my parents garage when I went off to serve the country. Four years later when I came back from the Navy it was buried under my dad's stuff. LOL. I have dragged it around with me not running now for 42 years with plans of getting it running when I retired. A recent divorce brought me to a new living situation more out in the country where I met a fantastic mechanic that loves to work on older Fords. It's now a badass machine with a sweet Proformance Unlimited 408 thumper in it. I don't plan on painting it at this time as it tells the story that the car and I have been through. Gonna take it to the car show and put a touch me sign on it.

Special shout out to my dog Smoke who tolerated putting Shelby stripes on him for the picture.

Very grateful to the entire Proformance Team.

Thank you

Hi Steve,

Just thought I'd flick a few photos through of our 1934 Chevy Sedan rod build, with the engine you supplied us...its all fixed in place on the newly built chassis with the Kugel front and rear ends all in too. Looking great so far I reckon 🙂
Anyways - I hope all is well and business is still pumping along.

Cheers & regards,
Grant M.

Steve,
Just wanted to send you and your crew some pictures of my 35 hot rod with one of your 383 SBC stroker engines. It's riding nice I'm waiting for my state inspection before putting it out on the road.
I'll swing by your shop so you can get a closer look.
Thanks for the great looking and running engine and transmission. And especially for the help on the small details I couldn't figure out.

Thanks again and I'll see you soon

Thank you to Doug and Steve. This was my first build and these guys did an awesome job on my 408 stroker. They helped by explaining the full process of the build and answered all my questions.
These guys are great to work with and do fantastic work. Love my engine!

Hey Guys ,
Just wanted to send an update on my 56 Ford F-100.
I'm sure u recognize that 347 stroker , Cant wait to get it started so i can hear that thing Purr especially with the cutouts !!
Thanks again guys , after researching many engine builders I'm sure i chose the right one.
Dean Sweet

Doug and Steve thanks so much for such an awesome motor can't wait to get her started and hear her purr especilly with the cut outs !!!

The 383 stroker that you built for my 77 vette is just awesome! The car sits in a storage unit months at a time. However, it always fires right up without any hesitation and runs fantastic! I can't tell you enough good things about this motor and how reliable it is! I haven't have one single issue with this engine. thank you for building me a FANTASTIC motor! you guys are the best.

Just wanted to drop you a note. I bought this 347 from you in December and have put about 5000 miles on it so far. We just got back from the Falcon Nationals. We drove from just South of Baton Rouge to Wichita Kansas and back a total of 1665 miles. We had absolutely no trouble with the engine. It still has plenty of power and runs great. Everything is still clean and dry, no water or oil leaks anywhere.We made the trip on just under 100 gallons of gasoline which comes out to a little over 16.5 miles per gallon. This is driving 75 mph with air conditioning running the entire time. Feel free to post this on your web page or call if you have any questions. Thanks. Sherlin

Steve, My name is Mike C. I'm the mechanic that installed the LS you guys built for Robs 69 Chevelle. I would like to say you guys did an awesome job. You delivered exactly what you said you would. A turn key engine that produces gobs of torque and HP. I literally had to do nothing after the install except program the computer to turn on the fans. Great job. I'm including some pics of the completed job.

Dear Steve:

I wanted to let you know how much I appreciate the quality and precision put into building my engine. After 6 years my 461 Pontiac stroker is very strong with no leaks. I haven't even changed the spark plugs yet. I would never consider anyone but Proformance Unlimited to build my engines.

1969 GTO Judge

A big thank you to Steve and the crew at Custom Crate Engines.
My 64 1/2 Mustang turned out better than I anticipated. I receive compliments ever time I take the car out for a ride.
Steve was instrumental in helping me with my install and set up.
If you want the best, buy from the best !
Custom Crate Engines !!

thank's to you guy's i love my 347 stroker that you built for me it's torque powerfull it not bad with gas you are very nice and profasional people iM very please keep up the good work thank's a million

Steve,

The car is being broken in as I type. I have about 100 miles on the new engine and it is perfect.

I can`t thank you and your team enough for building this for me and assisting me through the process.

I had it installed over a weekend and then did the modification for the vacuum.

Here are a few pictures. If there are any certain pics you want let me know. My son has a video of the first start and walk around to verify everything was good.

Mike

I have had my 302 Windsor for around 5 years now,and i must say it is faultless and exceeded all expectations.
A quality build couldn't be happier, the only time i have had to put a spanner on it is for servicing.
A big thanks to the guy's at proformance unlimited.
Craig Pryce

This is the difference in who you get to build your crate engines.
We contracted Proformance Unlimited to work with us in building the 408 Injected Roller Windsor for the XY build for one reason.......experience!
There have been literally hundreds of "Crate Engine" companies starting up since they became popular 🙄 but nearly every one of these are simply "fitters".....they just assemble a heap of parts out of the box and bolt everything together into something that resembles an engine 🤔 Nothing is matched, inspected, measured or tested......you get it in a box bone dry and just prey it all works.....which 9 times out of 10 they don't !!!
This is where crate engines got their bad reputation, from these types of pop up builders with no experience trying to cash in on a lucrative market 😡
We chose Proformance for their 30 odd years of experience in this industry and worked with them over many 2:30 in the morning personal phone calls to Doug and the staff the whole way through the build to plan, discuss and modify components to get exactly what WE wanted, not some catalog engine. Even through shipping and customs dramas they were there the whole process helping out from their office in New Jersey to make sure everything got sorted 👍
Their customer service and backup has carried on long after they "got our money"
The 408 turned out a great engine and came with all parts receipts, build pics, dyno sheets and even a video of it's dyno runs😁
Won't get that from any of these internet crate builders !!!
I highly recommend Proformance Unlimited to anyone looking to build their own crate engine 👍

im very please whit my engine it run strong its reliable i go everywere and the people they are very nice they take the time whit you anserwering all youre question im very happy 347 stoker 430 hp and 450tq thanks alot sorry for delay

WOW!! Great experience dealing with Steve. He was very helpful with any question and resolving any questions.
This is the car that your 454 engine promotion video went in. It was the 2017 Second place winner in its class at World of Wheels in Pittsburgh and First Place 2017 Street Achievement Award in paint. The car and 454 engine are head turners.
Tim Rodgers

Steve,

Here are some pics of the bad ass 427 stroker you guys built for my 1966 Chevy II.

Hey Steve,

Hope all's well with you and Doug in the new shop. Just emailing for some feedback on the 408Windsor you built me a couple years ago. All's running great still, the motor hasn't missed a beat apart from MSD burning out which is nothing to do with you guys. I appreciate your after sales service and always picking up the phone to answer my many questions before and after it was built, it has plenty of power and runs smooth as, exactly what you promised me. I'll be in contact soon for some upgrades/tweaks to see if we can bump her up to 550hp :-> I've attached a couple of photos of the car it went into. A 67 S Code GTA Fastback, hard to find over here in Australia

Take care
Carl

I would like to thank Steve, Doug and all the team at Proformance Unlimited for a fantastic job on my 400 HP 347 build that actually did 360 HP on the dyno. The quality of craftsmanship was much better than it needed to be for my satisfaction. The attention to detail was the best I have ever seen. I would highly recommend Proformance Unlimited to any one looking to purchase a high quality crate engine at a fair price.
Thank you Steve for an outstanding job.
Teddy Spencer

Hi Steve,

I just wanted to actually follow up with you on that Olds 350 you guys built for me. You may recall that the initial installer wasnt truly prepared to bring the idea to fruition. He installed the engine, but it wasnt right. In fact, I didnt even drive it....lol....I knew all I had to do was get it in the right hands, though, which I did when I got it to Chris at Ludlow's Speedshop. Now, that motor is smokin hot and Im mighty glad that I went with your company! :-)

Cant wait to do business again, in fact!

Thanks again!

I purchased this 383/510 back in 2004 and now have it in an 85 Blazer with 5 speed. 13 year old motor runs better ever! Fastest combo I've ever had. Proformance Unlimited delivers QUALITY performance.

In 2014, I decided that I wanted to upgrade and rebuild a 1937 Ford Cabriolet that had been my father-in-law's for over 20 years. So....I began with the engine and transmission. I contacted Performance Unlimited at the time in NJ. Steve worked with me to design the engine of my dreams for this car. We build a 383 Stroker using a GM 350 block. This engine is a standard 400 HP/500 ft. lbs of torque. The engine dynoed at 450+ HP and 520 ft. lbs. of torque. I couldn't be more pleased with the build quality and the look of the engine. Now this engine sat on the shipping pallet for the next 2 years as I rebuilt all the mechanicals around the engine and finally dropped it in the car in 2015. On November 4, 2016 I started the engine and began the test runs needed to ensure the drive train ran correctly. I could not be more pleased with the performance of the engine. It is a "BEAST" to say the least in this car. I was very pleased with the support, discussions and direction provided by Steve along the way to ensure that the engine I wanted performed the way I wanted. That support was very much appreciated and contributed greatly to my following their direction as the installation and fine tuning progressed. The result........I have a wonderful car with an incredible engine that I am very happy with and would encourage anyone seeking to build a custom engine to contact Steve or Doug. Also, Kim Attanasio was wonderful to work with as well. She worked hard to connect me with the people in the shop that could answer my questions as they came up along the way. Thanks so much.

Kevin
