Performance Clinic - The Engine Company

"Not really sure how best to rate this, so 2 it is. I'm sure they do a good job at your standard 350 Chevy, or anything that isn't too overly complex.. but this was not the case with my 400 Olds. They were behind the 8 ball from the start as the previous shop I had the engine dropped the ball on their end, so the first attempt at assembly was put on hold due to the wrong bearings ordered, and bent rods. After I was able to locate new rods and pistons I was put at the end of the line. They did however order correct bearings, new valvetrain components, etc. Once assembly began again, all seemed to be well until pickup. I was supposed to have the carburetor rebuilt and run on the dyno.. which didn't happen. The engine was run on the dyno solely to break the cam in with a carburetor they had in house, but was unable to make a pull. Once I got the engine in the car, we spent 3 days chasing our tail only to realize it was 180° out from where it should've been. I also spent a little over a year, multiple carburetors, changed intake gaskets multiple times, changed spark plug type, chasing a low vacuum/poor performance/low compression/poor timing issues only to finally break down and verify that the cam was 16° retarded. At one point I called and was told the timing set supplied did not allow the cam to be degreed, even though the cam card required it to be installed 2° advanced. They will not rectify the issue without me pulling the engine and scheduling it back in the line.. options that I don't have. So after meeting thousands of dollars, this engine is currently apart in the car in my garage while we change timing sets to allow it to be degreed as it should be. In summary..if you want an assembly shop- Performance Clinic will suffice. If you want an engine builder who will make sure everything is correct.. look elsewhere."

"My 4.6 2v short block was assembled here. These guys did awesome work and have really came in clutch on their own time when they didn't have to"

"Absolutely fantastic company. We use them for everything machining. Highly recommend using them for all your auto machining needs!"

"Would not recommend. Did not install the o-ring on my boundary oil pump when assembling the bottom end which caused the pictured oil leak on first start. I've also attached a picture of my receipt with my info censored, so you know I'm an actual customer. When calling about the issue, I was polite, yet the person on the phone was rude and they did not stand behind their work. Disappointing."

"Family business of Hot Rod Experts... Love to see the dragsters on the property. Dave is rebuilding my Vortec 383 and took plenty of time to go over what I wanted and then Dave explained what was was better or not. His live for motors is Amazing. Soon my truck will come home and I will come back with an update. Well my High Performance 383 engine runs smoothly not a bad way to keep my 1996 Chevy running... Thank You All..."
