AVS 2 CFM???

That is a great street carb. For the street use you loose throttle response at low end if you go too big.
I ran a 500 AFB on a 451 stroker and crushed a 427 Chevelle in the 1/8th. Yes he passed me in the 1/4th as I couldn't top end with a small carb.Later I went with a 750 and was running 11.90's in a 65 B body street car.
Right now I run a single 800 AVS on a 472 Hemi on the street.No plans on racing it.
