Why would it make the same or less on a 347? if its running slugish my guess there is something else wrong. I had a e cam before and it was no too bad. with stock long block and the ecam i made 247 rwhp.

my stock motor made 276....

still think the E-cam is good?

assume stock heads, stock cam, and the stock carb, but on a 347 stroker. what kind of hp numbers am i looking at? the higher displacement and stroke must account for something?

not much when you choke it.......since you have more cylinder volume to fill now and are using the same stock cam, stock heads and induction that were designed for a 302 stroke, how will you effectively fill the new found displacement adequately to it's fullest potential?? you won't and you will gauranteed be under 300 rwhp then

a 347, with the same compression ratio as a 302, and stock 302 h/c/i.... MIGHT make 30 more HP
