Hello all,
Today I looked at a newly assemled crate engine with the following specs- High nickel 2 piece rear seal block, 383 Eagle rotatiing assembly, flat top pistons, Comp Cams 270 HR hydraulic roller cam, Comp Cams roller rockers, Edelbrock RPM Performer Air Gap intake, and MSD HEI distributor.
The cylinder heads are nothing special- Chevy 1.94/1.55 heads. Compression ratio is estimated to be 10.0 to 1.
The owner estimates the horsepower is 410 and the torque is 430.
I have my doubts with those heads and the mild specs on the roller cam.
We will most likely run a quick Fuel 680 or 700 cfm carb on this engine.
Based on the great experience level out there, does anyone have an opinion as to the horsepower and torque from this engine combination?
If I were willing to add just a little higher quality cylinder head what would you guess the horsepower and torque would be?
Thanks for your help.
John T.
