My plan is a pro street deal. Maybe run it down the track once just to see, but not a definite etched in stone hp goal, but 900ish would be nice. I'm thinking 11.5:1 or 12 572 using the stage 5 replacement heads which are cnc ported and flow just over 400cfm. Not sure where that combo will land me, but i think its close to my goal. Looking over on Arruzza's site, he has what i want. Looks like his Ross pistons might fit the combo well . I'm really liking the Bill Mitchell block at this point as well, haven't found any real negatives about it yet. Everything still on paper as i'm learning.
