Not for sure if this is the right forum but. How much hp can these flow numbers support? This is out of a older set of Brodix -10 heads.


These are flowed at 28 on a 4.030 bore

int exh lift
195.4 133.5 .300 at 27.97
241.7 162.1 .400 at 27.96
264.5 183.6 .500 at 27.95
274.3 196 .600
283 203 .700

The exhaust seems good compared to the intake.


This will be on a 383 with 12 to 1 comp, a single plane intake, and a solid roller.

 

Roughly 580FWHP everything else being correct.

 

I was always told a good rule of thumb to ballpark it is 2hp/cfm.

 

I'd also go with around 580 hp max.

 

It's a good rule of thumb, but that caveat of "everything else being correct" is a big one. I mean, a 400hp STOCK head LT1 would be ~2hp/CFM. That is perhaps do able, but not easy.
