Thread: What can I expect? (New 454)

Tweet

Hello you all, I'm new to this site and before I ask my question I just want to say I think all of you are very knowledgable on your info and it is much appreciated for your advice. What I have is a .040 over fresh 454 (casting number 3963512) with flat top pistons, powermax cam .534 int, .553 exh, duration 286int/296exh . Closed chamber heads (casting numbers 3872702) I used felpro head gaskets .039 thick. Also I'm running roller tipped rockers, mallory ignition, holly med rise intake, edelbrock 750 cfm carburetor, full length headman headers. With what I listed above what can I expect in HP and torque, what kind of compression will I have with the 702 heads and flat top pistons. Lastly will my engine lope with the cam I listed above. Thank you very much......Also engine is still on the stand so if you all think I could improve on what I have your suggestions will be most welcomed.....Thanks again.
