Roughly what sort of BHP figures should I get out of my 331 stroker?
Its 331 stroker, h-beam rods, stud girdle, 9.5:1 comp ratio, world windsor sr heads, Edelbrock performer plus cam, scorpion roller rockers, MSD ignition, Edelbrock intake and Holley 600cfm carb.
Is that enough info for a rough guess?
Thanks in advance.
ps stated it today for the first time MMMMMMM loverrrleeee. Wanted a nice smooth tickover and thats just what I've got.
Thanks again
Simon

We built a 331 stroker with 10.5:1 compression and the World Products Jr. Heads. Cam is around .550 lift, 234 duration at .050. Victor Jr. Intake. It came out to 445hp at 6500 rpm. My guess is you are in the upper 300 range. The Sr. Heads might be a little too much for your cam.

Sounds like a plan to me

I agree the heads may be a little bit of an overkill for the cam, but as I only paid £50 (about $75) for them new, I thought I'd suffer them
