1137 times 1.5% = 17 HP just from that mod. (lower HP assumption is 3% per point. 1154 HP right there and he has a 567 inch engine now.

1137 / 554 = 2.05 per cid. 13 cid more so 13 times 2.05 = ~26 HP.

1154 plus 26 HP = 1180 HP. And I would hope that the "bigger carb" and Marcella Manifold tweaks would get him 10 HP. so now we are at 1190 HP before we even get to the Vacuum Pump vacuum increase.

All of my stuff is typically based off of historical data. If the numbers are valid.

Theoretically I cannot argue with your post Tom. But my practical side says NFW.

Yep, .100 more stroke with no mods to the heads or any part of the induction system or cam timing. Rpm will come down from before or should. But hard to say what the other stuff will do to rpm??????

It's 15 CID...

I'd bet money that if a fella had Marcella run his ehead program and a customer "improved" the valve job. Picked his own cam and "saved" $500 on pistons and rings.....that fella would fall 150hp short.
Who's Gary h ?
