David:

I think Holly made a 4150/4160 carb in both 600 CFM and 750 CFM. I am
not sure which is which though. I think they are both vacuum secondary
if I remember. I have run both a 600 and 750 vac on my 302. Both
worked well, and the 750 seemed to run harder given my kind of radical
hydraulic cam. It was the one designed for up to 6500 RPM if I remember
right. You can probably find out the CFM by getting the throttle plate
sizes to someone in the know.

By the way, did you check out that new fel-pro EFI setup?? I think I saw
it in Hot Rod last month.

On another note, can anyone tell me what the cfm for a Holley
