im getting a mach in spring. i know im going to supercharge it. from what i have read they hold about 450rwhp but i know theres always the ppl that push it and make more. are a lot of ppl making 450-500 rwhp with stock internals? if so whats the safiest power adder to get their, centri, roots or turbo?

not on boost because the mach's have higher compression pistons that aren't made for boost. You can get 400 but I doubt there are many if any running boost and making 500 to the wheels on a stock short block mach.

I read about one guy on the registry making 507? I think on the stock block. But that is DEFINATELY not the norm. I blew 3 holes in my block at 417/413. It was pretty spectacular.

wow so you saying its higher for machs to be making 400??? GT's can make 430 rwhp but they have lower compression so to run higher boost

it will run it just fine, just got to be carefull on tuning. the VE of the heads will allow a little more power, but you have to be easy on it at the same time. 450rwhp is a "safe" recommendation, but they can hold a little more if done right.
