Thank you guys so much for building an awesome engine! This 383 stroker screams at 400 hp! The shop that installed my motor was very very inpressed! The engine was shipped already tuned and all dialed in! They had a Roush mustang and they said that my engine that was built by profornance unlimited was heads above the Roush. The roush couldn't touch it! The car drives beautiful. You guys are truly the BEST! Thank you for this awesome engine!

Finally got the transmission issues behind me and have the C6 installed. Can't thank you enough for the awesome motor! Here is the burnout video you asked for. I will be racing at Hemmings "Musclepalloza" on Labor Day weekend and will let you know how it does.
I will be using you again if I get another project in the works. Again thanks for the fantastic motor.

A quick update on the Chrysler 360 you built for me.
1000 miles now covered and it just seems to get quicker. Even in a heavy Dodge Stepside the performance is awsome. Leaves a lot of others behind.
No leaks. No seeping and I have never had to adjust it.
Well done to you and your team for a tremendous build. I would recommend you to everybody.
Just a quick update on my 360 you built for me.
I have about 300 miles on it now. No leaks what so ever. The motor is freeing itsself up and getting even more responsive each outing.
It surprises a lot of cars that pull along side lol.
Please let your team know and say thanks from me I cant fault the looks and power of this motor.
Will keep in touch and let you know how its performing.

I just wanted to thank you guys for the great job you did on my motor. I
just recently got the car on the road after a 2-year frame off Resto Mod
build. The motor starts first crank every time and has insane power... not
to mention it is quite a crowd pleaser to say the least.
Again, thank you!

All that I can say is wow!! I think that beast will shove that mustang around like crazy. This whole process has been a pleasure and I am so excited to install this engine into the car. My business partner said the experience, pictures, and dyno hit sold him. I am sure he will have you guys build an engine for him in the near future. Again thank you so very much for your patience when I called. I will send pictures when this project is completed as well as some video. Have a great weekend.

Doug, Steve and the Pro-Formance Unlimited Team --
Just a short note here to let you all know how pleased I am with my 302-380 HP custom engine by Pro-Formance Unlimited. The engine runs great and is every bit of product you advertised it would be!! Quite the improvement over the original 289. The quality of parts and workmanship are evident in the resulting performance. I can rev it up to 5500 and drop it to idle with no hesitation. It's great to have that confidence of knowing that what's under the hood will be there when I need it (or just "want it"). It was a pleasure dealing with Pro-Formance Unlimited from Kim at the front desk, to Steve in getting my sales order spot-on (yes, he did a great job in translating my non-technical specs to an engine configuration that met my needs) and to Doug who I watched build my engine via the shop-cam and starred in the delivery video. Thanks again guys (and gals). I'll definitely recommend Pro-Formance Unlimited to anyone seeking a custom engine build.

Hi Doug and Steve,
Just to let you guys know we dropped the motor in our 85 Camaro 2 weeks ago and put a set of SLP headers on it . It sounds fantastic The throttle response is right there. We're still waiting for the trany delivery. The day we fired it up most of my friends came up to our house and were very impressed with what they saw and heard. thanks for your great service (1-1/2 weeks for a complete turn-key set up). I'll send you pictures when the car is complete.

Doug And Steve,
I have been driving around now for about a week and I can certainly say without a doubt that you are a master craftsman. The feel of the engine is incredible, it did not respond this way when it was new. Everything is so tight and neat that I almost feel as if I am driving a new car. The workmanship and the level of detail exhibited in the rebuilding of this engine can only be described as excellent. I want to thank you for a job well done. You can be sure that Performance Unlimited will receive my highest recommendations.

Dear Steve & Doug
I wanted to thank you for the great job you did on my 351w, not only does it look fantastic it run just as good I'm very pleased with the service, your price quote you gave me was right on target and delivered the level of performance I was looking for. The fact that you were able to pick-up and drop off the motor with a fast turn around made it all the better experience dealing with your company!

Hey guys this is Derek Hagner I bought a 383 Stroker (Edelbrock special) one of ten in Dec. of 03 and I'm extremely happy with it. You guys did a great job a matter of fact you have it posted under your Chevy performance category, it's the one with the yellow block under main heading. Anyways I wanted to say thanks for everything, but I have a question. The engine sets in a 67 Camaro with a TH 400, 3000 stall, 1 7/8 super comp headers with 390 gearing and I'm in the 6000 to 6500 rpms and not even down the 1/8 mile, how far can I safely rev this combo? This engine was upgraded with Keith Black pistons and air gap intake. I've installed a digital rev limiter to protect the engine but it sure is pulling when it kicks in at 6500 rpm. If the engine can handle more revs do I need to upgrade the distributor to something that can withstand the rpms? Again the engine is awesome Doug did a great job. Thanks for all the help and hope the new shop is going smoothly.

Dear Doug & Steve
Just wanted to drop you a letter to let you know how much I am enjoying my car after all the hard work you guys did. Not only does the engine sound great but also performs like a champ. I have more power than I feel safe using.
I have to admit I was a little nervous when the tow truck came to pick up my 1968 Dodge Polara back in January. I only knew your company through what I read and saw on your web site. I was pleasantly surprised when you called to let me know that my car had arrived safely and you did a thorough inspection to make sure that no body or paint damage occurred during transit.
As you know, I kept adding more and more work to be done to the car. First it was the engine rebuild, then the drum to disk brake conversion, then the new gas tank and sending unit, then the headers, then the leaf springs, New rear drums and rotors, and finally stall converter and high performance transmission. You handled all my projects with enthusiasm and professionalism. When my son and I came down to New Jersey To "visit" my car, you were fantastic. You gave us the full tour of the shop, showed us my engine and what work was already completed. You guys dropped everything and treated us like "VIP"s.
Thank you so much for your help in meeting and exceeding my expectations for my car. I highly recommend you to people I meet at Mopar Clubs and shows. Keep up the great work and I will see soon when I bring in my Z28 for work.

Just wanted to let you know that the engine is in the Camaro. I started it up and am very impressed! It was rush to hear it run .I let it Idle for thirty five min. Now and then I INCREASE THE RPM TWO 2000,THEN 2400 ,never hit it hard, Though it was like a horse wanting to go! Hope to get it on the road very soon. The throttle response is awesome. The temp, never got above180* I enclosed a few pic's let me know what you think.

Doug and Steve,
I just wanted to thank you guys for the great 383-510 horse power stroker you built for my 81 pickup. Three days after it arrived, it was in my pickup and I was roasting the tires right out of the garage. I love beating on all the mustangs and Camaro's around town off the light. It was a great relief to me to able to call Steve and ask him question during the build process. Thanks again guys and will be calling to order another engine for my next project.

Friday I went over to the restoration shop to get my first look at motor and transmission. It appears that you people did a real fine, they look great. My mechanic said your people did an excellent job shipping these items.

Hey Guys !!
What an absolute pleasure it has been working with you. The entire process of my motor build, from conception to completion, has been more than I could of hoped.
The motor runs flawlessly. I just returned from a small car show in Prairie City, Oregon. The accolades were amazing. Many of the show participants were very imprested with the sound, power and appearance of my new 350/420 for such a fair price. The engine has been a perfect compliment to my car.
I want to thank you for all you have done. As the car nears completion, it has been my great pleasure working with all of you. I wish you much success in the new year to come.

Dear Doug & Steve
It was a pleasure meeting you guys when I picked up my engine (Chevy 502) when I pulled up and saw the engine sitting there I was amazed it stopped me in my tracks I can't believe the quality and craftsmanship of the engine you guys are awesome I would recommend you in a heartbeat to anybody when I dropped the engine off at my sons work every mechanic in the shop stopped what they were doing to look at this masterpiece they could not believe what this engine looked like they were drooling over this engine when they ask me where I bought it from I proudly said Proformance Unlimited once again I would like to thank you guys for one hell of a engine job well done when this project is done I will send the camera back to you once again great work thank you so much.
Doug and Steve, I can’t thank you enough for building my 1970 Pontiac 400 with 10.75 to 1 compression...
Doug and Steve,
I can’t thank you enough for building my 1970 Pontiac 400 with 10.75 to 1 compression, new Edelbrock performer rpm manifold, new Edelbrock 750 carburetor, and speed pro forged pistons. You painted it the correct Pontiac blue and it arrived beautifully put together. Thanks for taking the time to build me exactly what I wanted. The engine has worked great now for 4 years or so and has plenty of power(probably around 400hp). It even held together when I accidentally revved it to 7000 rpm a couple of times. That video of it bench revving to 7200 is unreal. I installed back in my 67 GTO and it looks fantastic. It is usually one of the best looking engines at cruise nights. I am enclosing some pics for you. Also, I can’t believe you built such a great engine with so many new parts for the low price you charged. It cost me 30% less than if I had built it in New Orleans including the shipping both ways By the way, I might be ready to take another step for even more power. What would suggest next? I could send you the heads for porting and swap the cam for something more radical. The current cam is an angle with about 228 and a low lift of .49. It is pretty tame and I would like something with more of a lope. It is strictly a street cruiser, so I don’t want to sacrifice too much drivability. Could you stroke this engine out for more cubes than the current 412? Or would you suggest I get a 455 block and stroke this for monster torque with great drivability? If I do a 455 I will want to add a turbo at some point when I can afford it. Glad your business is doing well. I always recommend your shop to every single person I meet that needs any type of performance engine build. You are the best. No one else will ever build my engines.

February 18, 2007
I want to take a few minutes and thank everyone at Proformance Unlimited for their professional dedication on the 350 440HP "high roller" engine that was so skillfully assembled for my 68' Camaro. after getting the engine compartment all ready I dropped the "roller" in and it fired up on the first crank!
I really appreciate the staff taking my calls on the questions I have had along the way. I can't wait until spring time so I can get it out and really enjoy the massive horsepower this engine is cranking out. My first small run showed me the potential this car can have; it sure was a major upgrade on the engine that was running in the car before.
Again my many thanks to the entire team, what a great job!!
Well, Steve sorry it took so long to get with you on the first stage of our installation of the Great Crate 383...
Well, Steve sorry it took so long to get with you on the first stage of our installation of the Great Crate 383 you guys built for my 34 Ford. It arrived in the afternoon by UPS and we unloaded it, the UPS man and pushed it into my garage. It was like someone spread female hormones in the neighborhood, before I knew it all the men in the area picked up the scent and were drawn to my garage. First it was the UPS man refusing to leave until I opened the box, then there were 8 guys standing around waiting for me to take the cover off. I suddenly sprung to my tool box for a box knife but before I got back all my friends had popped the box top and were all standing around with a Woodie ""Cheap Male Viagra" It was a site to behold" we all stood around this beautiful motor with beer in hand and wearing sun glasses because the reflection from the motor caused extensive glare, a guy can never have to much chrome or horse power you know, we all conversed about how it will look and what I should do to the "34". You guys built one hell of a motor cant wait to get it into the car and fire that Baby up for its first run, stay tuned for the next episode, when the motor goes in and the pictures begin. In the mean time I'm going to throw a chain around it and wear it around my neck " Man Bling" PS. Steve I talked to a friend of mine Mark Archer of Camas WA. About you and he also ordered a 350 for his ''74 Vet. Still can’t believe the great job you guys did and what a work of art

Hi pro guys,
Just dropping you a note and a few pictures of my BEAST!! She looks great in the engine bay. You guy's are everything you advertise and I am glad I found your website. I am chomping at the bit to get out and chew some ass on the road. Proformance unlimited is confident in their product, and they provide the power they preach. Keep up the great work guy's. P.S. Looking for a 56 F-100, and going to stuff it with a little old motor from the boy's in Jersey.
