Well, if you are talking 300 whp, you better have a manual transmission for this attempt. Superdave is over 270 whp but with a 3500. Colin Wahl is at 222 whp and his setup is posted here. I ported the heads and he is running a 1280 cam, which isn't extreme but he is on the stock pistons.

I built a motor with 12.4:1 compression and my 1331 grind, ported 3500 top end, crank scraper, knifeedged crank, polished rods/shotpeened, balanced rotating assembly, 65mm TB, etc. He hasn't dynoed it yet or run it at the track but from his stories, its crazy
I don't think its 300whp but with the grand am SE trans and torque converter, the full potential isn't going to be realized either.
