Another guess the Hp thread

[650jetmech]

Engine goes on the dyno next week. Heres what i have, Eliminator sportsman block 4.39, 4340 Liberty crank 4.30, Oliver rods, Mahle pistons 12.8 CR, AFR 295 heads port matched to an AFR Dominator flange intake, minor plenum porting, 1150 Holley, Solid roller cam 272/280 .774/.770 109*, 1.8 Comp Roller Rockers,  2” primary headers for now. All I want is to crack 800 but i think it might just have more than that in it. Any guesses?

I'd quite frankly be surprised if it didn't exceed 800 hp.

Remove the pinch(s) in the plenum corners just below the carb flange.

You were only 6 horsepower off good guess!!

Nice Numbers and glad you got it running.

I think 5Points has close to the same cam, or at least it has the same .050" duration and LSA with .730"ish lift.

Thinking out loud, would have 1.8 rockers have picked his 763HP deal up any?
