Thread: largest 2 barrel carb?

Tweet

Some friends and I were talking about sizes of carbs and were wondering what the biggest 2 barrel carb made was. We came up with holly 500 cfm. Were there any bigger ones made?

on round track race cars ive seen what they say was 800+ cfm's in a 2 bbl. carb. in classes that couldnt run 4 bbl. they cost about 800.00. the biggest one i ran was a 600 cfm.

Edelbrock makes a victor jr.sportsman 2v manifold good for up to 7000 rpm. or you could use the adapter for the 4bbl victor jr. and turn it on up there. I have heard of reworked 650 2bbls. flowing at over 800cfm.

The biggest one I could find was the Holley 500 . Center bowl and 50 c.c. accelerator pump. 0-4412C I've heard of smallblock's running 10 second quarter miles with these.

i think maybe the 500 might be the biggest cfm you can buy across the counter, but i know Barry Grant Inc have reworked 2 bbl carbs. up to 800 cfms.

The biggest one we could find was 500 but like you say, Grant does modify them. Thanks all for the info.
