So our highest HP on the Dyno today was 297. We need to make over 335 by tuesday of next week with what we have. Might have to resort into putting dry ice on the manifiold to up the power but wanted to do it mechanically instead. Anyone have any ideas. here is my current set up.

Chevy small block 350 with stock internals (pistons, crank, rods.)

cast iron Bow Tie heads (2.02/1.60)

Hydraulic .515/.520 lift Cam 310 duration

Single Plane Vic. Jr. manifold

750cfm Street Demon Carb

1.6 roller rockers

I pretty much can change out the carb, manifold, and mufflers at this point.
We have every carb cfm known to man available and 2 inch spacers.

Any help is appreciated!!

Thanks sooooooo much!!!
