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.
