My eingine is close, 11.0 to 1 and my cam is .600-.600 260-260 @ .050 and made 594hp and 540 ft lbs. I have the same heads and intake. I dod use a 830 Nascar Crab, but the engine only used 535 cfm, so the size carb should not matter

I have a dart block 383
13.54 cr
ported afr 210 heads
ported super victor
970 cfm 4150 carb
cam is 640 lift with 272 and 264 duration solid roller
through 1 3/4 cramic coated headers
peak torque was 525 @ 5300 rpm

Guess what on another dyno i would might have made 640 hp, so what i used it for was a tuning tool

I agree, we've been getting alot of these HP requests latley, just look what bowhay' HP guess got us into.

If in doubt go dyno the engine or put it on a chassis dyno after its in the car.

I know your curious about your combo and so are we but really all we can do is guesstimate.

Build it, stick it in there and drive it like you stole it.
And like Paul said if it don't do it for ya, then pull it out and try something else.

But if you just have to have a guess, I'd say somewhere around 500HP give or take 50.
