Needing to get a 4BBL manifold and carb to run my 406 sbc on 1/4 mile dirt track. So many options, I need help. Going to run my KP 2bbl and "313" until I get the new stuff. Please let me know what ya think will work. Thanks, Race

We need a lot more info: Cam, heads, car weight, gearing, etc.

An Edlebrock Performer RPM intake and 750 carb would work great geared for 5800-6000 max.

Cam and valve's are too small to try for anymore than that. The cam range of 2000-6200 is more than likely for a 350 and will be 1600-5700/5800 in a 400.

I run a Holley HP4150 750cfm methanol carb, with an edlebrock air gap rpm intake. Works real good for me.
