Inliners International Forums General Discussion Hi Performance New 2 BBL intake on the horizon!

CNC-Dude,
That is a pretty sweet manifold! I don't reckon it matters all that much but... have you given any thought as to which 2GC's to use: the 1-1/4" flange(1-7/16" throttle bore) "Chevrolet" ones or the 1-1/2" flange (1-11/16" throttle bore) "Pontiac" ones?

All the small flange ones flowed about 197 CFM "in four-barrel speak" while the large flanged ones ranged in flow from 249 CFM to 308 CFM ( again, in 4bbl talk) dependent on the venturi size.

I reckon it might be easy enough to do both, if you were so inclined.
No big deal; just curious. Keep up the good work!
