Post your 12 second combos

[Gunner1]

Depending on what C&C program was used, those heads will make pretty good power . maybe 300cfm @ 28in , with that cam you should be in 525 ish net HP at the crank

Eric Weingartner flowed a set of the later CNC heads. Only 278@500. The early heads were done by MCM if I remember right. Those flowed all the way to 700.where it flowed like 335cfm. I’m gonna try to pull them this winter and finish porting them. The surface finish isn’t 60 grit, it really is deep cuts. They left a lot on the table. If I like how they come out then maybe a stronger solid cam and 1.6 roller rockers. I really liked the Elgin 1090P cam in my street SBC’s. 570/590,290/298,256/264, 84 overlap,99icl, 105LSA. Something like that and get the heads up to maybe 300cfm might get me an 11 time slip.

I dunno... I think you'll be pretty happy with what you have.. my old combo 64 dodge, very very similar. But schmoggger bottom end ran 12.10s at 111. Main difference? 28x1050 mts and a 5000 stall. If it had your bottom end it would be in the 11s for sure. Mine had ported 906s

I’m an old hot rodder, can’t leave nothing stock for long. But yeah I’d love a low 12 coffee runner.

Nice. That is a good ET considering the 60' and MPH!
When I had the 451 stroker engine the car would ET consistent at 12.50@110 MPH, with about the same 60' times.
What's the altitude there? Bandimere is (was) mile high.

We were getting very consistent 1.777s at 12.70s 106 with the 383 64 polara
