10.7 - 10.8... if all goes good... I'm assuming this is a track car... I'm curious why that duration... seems short for a 408(strokers like duration) and they like carb

Was thinking the same thing about both the cam and carb. Duration looks at least 10 degrees to short and it would love a 950 carb.

Guys, notice he is running only a 28" tire so he isn't too far off on gearing and converter.
When I had a home ported stock headed 408, .540 flat solid, 950hp carb, 4.56 gear, 30" tire, 4000 stall, 3500 lbs, I went 11.20 at 119.
He should be all over 10.7's.
But, with a little more gear and converter, easy mid 10's.

Thanks for all your input guys. First, I wanted to choose that cam because I did not want to let too much pressure out, and stay around 185 cranking pressure
Second, remember that I run a 904 with a low gearset, wich make a 3.91:1 act like a 4.30! You think it would be wrong to keep my 28'' slicks ?
What would you change?

I think with the right converter, trans and gear that the combo should be good for low 10s. My brothers car sounds quite similar to what you are explaning and it goes 10.50s @ 125 with a 28X9 Hoosier slick. You heads are bigger, cam seems more aggressive and the cubes are more than ours...I think you will go faster than 10.50s.
10.53 @ 125mph. 1.37 60 foot. Caltracs and Monoleafs, AFCO shocks.

I figured between 535 and 550 HP. Should go 129 MPH+ @ 3300 lbs.

I think the combos pretty good except for the stall. It could be higher IMO, more like 4500 to 4800. The gearing is fine, those 9 x 28 MT ,ET tires are actually 27.3" With the 3.91, thats actually the same gearing as a 4.56 gear and 32" tire.
With that 3800 stall and 3300# Im guessing 11.0s to 11.20,s
