In the quest to meet or beat current pro stock levels it may take another generation head design... Maybe on someones scribble pad because current blocks make it extemely difficult... impractical budget wise often sends Pontiac folks to the other brand... Not just little guy bracket racers... Make it easier for the guy with the scribblings on a notepad and that might encourage him to continue on an untried but promising path.

We WONT hit 2.7 per or anything greater without thinking forward. Bore spacing, cam tunnel placement, cam tunnel bore capability, and lifter bore spacing can lock us out of opportunities if we dont make revisions to the foundation that eases changes elsewhere.

We already seem locked to bore spacing... maybe a bit more deck width could be useful??? Room for other improvements/options in the deck??? Perhaps the cam tunnel can be revised for greater options??? Perhaps options in the mains area??? I already discussed the merit of easing lifter bore spacing and angle changes. Perhaps its time for an IA3 or MR2??? I think a lot of changes could be made to allow greater options and still be able to stay with all traditional pieces if one wants or needs to.

Bruce,
What has the Pontiac bore spacing got to do with producing 2.7 HP per ci? It has been done with smaller bore spacing, just look at Australian Pro Stock.
