He might be, but there is likely something he isn't telling you too. Either extra fuel adder somewhere or he isn't making the power he claims. Honestly, 300 hp on the rear wheels? That is a low 13 sec car. Or better. I would expect better than that. If not, he isn't making the power he claims. Have him stick a WB O2 on and make a quarter mile run and show you. Either he is running lean as heck, he isn't making near the power he claims (how much boost?), or he is running something extra like methanol injection to keep things sane.
My 301 Turbo pushed my 4030 lb Trans AM to 14.21@97.3 mph and that was a calculated 290 rwhp. Now put that in a lighter car, with more cam, a better turbo design (mine was awful), much better gearing, etc. That car should be darn close to 12's.
And you have to REALLY watch boost on stock hypereutectic pistons. They will crack. And what happens then sucks.... I melted #7 down on my 301 Turbo. And that was a well factory modified Q-Jet, 800 CFM, super rich "DX" rods and I STILL leaned out and lunched a piston.
