Finishing my build next week and dropping it into a 68 Satellite. I know it is a dumb question but can anyone give me estimations on this? Thanks

440 bored .30 over 9.5/1 compression
Speed Pro Hypereutectic pistons
Eddy RPM Performer Alum. Heads (84CC)
Eddy Performer intake with Eddy carb 750cfm.
Comp cam Advertised Duration 270/270, Lift .470/.470
TTI Headers 1 7/8
Moroso Baffled oil pan

 

Well Im sure there are a few that has Desk-top Dyno or some other programs but Im sure they will need more specific specs than you have provided....(ie: Crane Cam (slightly larger than stock) ) Just an observation.....

 

thanks I modified the specs

 

Go onto comp cams website and download their camquest program. Pretty cool and fun to play what if? Good luck.

 

is the compression 10.5 with the heads, or is it 9.5 after you factor in thermal efficiency?

 

I was told 9.5 to 1 . Not sure what thermal efficiancy is?

 

with aluminum heads, you lose about 1 compression (not literally) because the aluminum doesnt hold in the heat
so, your engine will put out power like it has 8.5 to 1
