Properly tuned I will say 525hp@ the flywheel, and mid to high 10's. Low 10's high 9's with a 150 shot. Maybe I'm just being generous though.
But good luck with putting it all together. Sounds like my car but with about 80 more c.i. and another point of compression. Oh and my guess is that a C4 will be more consistant, but no overdrive. A Tremec will be more fun IMO, and more streetable.
