590 H.P

I built a couple of 496's a few years ago and one of them was real similar to yours with the exception of intake and carb ( victor jr and 950 h.p holley ) it made 620 H.P

Congrats on the new engine.

Sorry, one more question, what headers? Diameter and length if you have both.

Re: 496 to be DYNO'D!
 

Hooker headers, long tube, 2" primary, 3 1/2 collector.

Re: 496 to be DYNO'D!
 

I set the cam on an intake center of 108 since I could not find an advertised ICL.
I used a primary tube length of 30" for the header.
I used a generic Dualplane intake since there is no airgap in my program.
I used 91 Octane and a running temp of 165*

616ftlbs @ 4,400rpm
589hp @ 5,500rpm

FYI.. Moving from a 108icl to a 106 or even a 110 did not show much change.

Re: 496 to be DYNO'D!
 

We'll see who's closest soon!!! Get yer guesses in people!!!!

Re: 496 to be DYNO'D!
 

In that case,, I'm gonna guess 615.5 and 588.5 cause I know how you came up with those numbers LOL. One of us is going to be really close <grins>

Re: 496 to be DYNO'D!
 

Marv, I used stock clearences, stock windage etc. So it might be a little conservative. With out knowing all the details, I tried to error on the low side.

Re: 496 to be DYNO'D!
 

I just got my dyno software installed yesterday an I see right now my software estimate an Super73's is right with each other.

Re: 496 to be DYNO'D!
 

What program are you running?

Re: 496 to be DYNO'D!
 

We ran a BBC on a super flow dyno with steel RHS heads and a solid roller that's in the .660's for lift with dual 750's it put up all most 700 HP.
You have a very nice head and comp ratio.
MY W.A.G is 640HP

Re: 496 to be DYNO'D!
 

640hp/620tq

Re: 496 to be DYNO'D!
 

Short delay on the dyno.... Should be friday or saturday...!

I don't know if you have done the Dyno experience but if you haven't it's cool. *I did it when we finished my motor and glad I did. *
