They did machine work on my big block Chevrolet and it was spot on. They also balanced my rotating assembly and that was right on as well. I have seen Borowski engines in a few cars at the race track. They make great power and seem to be reliable for the beating they are being put through. Understand though, that this is a business and a machine shop. Don't expect to have what you need done in 2 days. Quality work takes time.

I talked to a guy at the race and performance expo in st charles about getting my heads ported on a…read morels1 c5 corvette he said i will never make my goal of 450whp without a stroker rotating assembly or spraying it with nitrous. He said with a cam and heads and exhaust I'm a lost cause. Im looking to do a cam and heads I already have longtubes intake and tune making 376 rwhp but he said hes not familiar with 241 or 243 heads and then asked what an ls1 motor is rated for hp from the factory lol. Then he proceeded to say I should get a fully forged stroker rotating assembly or spray the shit out of it with n20 if I want to hit 450whp he said there is no gains over a stock profile cam lol and then he said the stock bottom end is like glass thats why I need a forged stroker kit to make power lol well lets just say I got away from that loser very quick and talked to some great people about a cam swap and if my 241 heads were worth porting vs buying a set of 243s thats all I asked and he spouted out all that trash talk instead of just saying he wasn't sure. The other guy that was there for borowski seemed extremely knowledgeable but there was a lot of people waiting to talk to him. Btw the guy that I talked to was trying to log into apple id for at least 2 hours he was struggling super hard with that the first and second time I walked by lol I hope he reads this and understands how dumb he sounded.
