Thanks Joe, for comparison though, a 302 runs 1.08 and a 351 or 400 ford runs a 1.21....so in relative terms, he ain't so bad! LOL!

Cool stocker though.

The air horn on the 2Gs is very small and restrictive not like the motorcraft 2Vs. Big difference.

Does anyone have REAL flow numbers for 2-bbl carbs?

[goinbroke2]

This is for the Fords;

Ford 2barrel CFM by venturi size --
.98=190
1.01=240
1.02=245
1.08=287
1.14=300
1.21=351
1.23=356
1.33=424

As most already know 4bbls are rated at 1.5" vacuum and 2bbl's are rated with 3" vacuum. I'd be curious to see what the chev 2bbl's flow.
Oh, and this is untouched flow numbers.

I have seen this list before. Do you know where it came from and some justification for its accuracy? Are these numbers @3"H2O?
