i have a 77 f100 with a 351m, when i add a 4barrel carter carb 700cfm,a comp cam dual energy cam and hooker headers,dual exhaust with glasspacks and no cats, how much horspower would my engine be making?
Too many unknown variables like
1) what is compression ratio?
2) what are intake valve size?
3) what is cam lift and duration at .050?
here is a cool site you can play around with based on your own knowledge of what you have: http://www.bgsoflex.com/roughhp.html
I'm guessing you will have about 275 HP @ 5500 RPM's

i believe you might get up to 190hp. 351m is not a race engine. i bet you could probaly pull anything you want though. I believe stock hp is around 140.
