Cam HP capability

Well I checked the Camquest program, and I am running version 6 - and I got how to enter the stroker data figured (you have to hit the enter button :o )

So I put in my head flow data, SP intake, 318 block with 4" stroke, 750carb, 10:1 comp, and -

I chose the "heavier vehicle/ 3000 stall" option.

It came up with the XS282s as the best fit! -

Here's the kicker - it reckons 456HP @ 6000 and 462ft/lbs @ 4500.

Thats 40 HP more than the Dyno 2000.

(My heads peak at 480HP, I can't see them making 456 with my combo.)
