does anyone have a ideal how much hp a olds 455 30 over stock piston with E heads 3angle valve job, edelbrock cam ,intake and 750 carb will make.
ctrl+bIf you're using TRW/Speed Pro pistons, .003-.004 piston to bore clearance. I'll agree with 400hp. Sorry about the bold it won't turn off.
Call Bill Travato at BTR Performance in Rochester, NY for a cam. Have all your specs ready; he's going to ask. The Fel Pro head gaskets are .041, and that kills compression. Use some thin Cometics.
Tapping the B wasn't working.....
Torque comes with displacement generally. Hp is torque over a given timeframe.
Just putting a 455 together with stock 1970 spec parts you'll get 300hp. So bare minimum that. With your combo id say 400 is a good estimate. Got a dyno shop nearby? Wheel hp and/or 1/4 mile et will give you a good guess.
