If it's a street setup, RPM Air Gap. It might make a bit more peak hp with something like a Vic Jr, and still run well on the street, but a single plane might not make any more average top end power if you're shifting it in the 6's than the Air Gap.

The Street Avengers are decent carbs, I had one, but for a performance setup spend the money on a good carb. I'm running a Quickfuel right now, badass carb. EVERYTHING is adjustable, even on their street carbs, jets, air bleeds, idle feed restriction, power valve channel restriction, even the metering blocks can have restrictors placed in the emulsion circuits, or you can upgrade to a fully adjustable 4 or 5 circuit emulsion metering block. Basically you can tune it as accurately as an EFI setup, and their customer service is excellent.

Victor Jr. + you may want to consider a 750 carb instead.

carb isn't deffinate yet, i have the 670 so i was gonna use it but in not against another. also this is a street strip but mainly street.

symonds86

also my cars a 5 speed don't know if it much matters but i though i would throw that in

grabbem88

hmm what did the guy who designed the cam say to use?

air gap???come on now are you serious?you are not going to lose any tq with a vic jr with that combo

mjr46

for a carb set up, sell the 670, run at least a 750, that's what i WILL be installing on my 347 soon, pro systems or biggs performance for carb choice

symonds86

what would you suggest for intake mjr?

mjr46

YOUR COMBO APPEARS TO HAVE BEEN designed by CI and most likely the standard there is a victor jr.......so go with that as others have stated, I had a race prepped 750 designed for my combo by one of the above carb places I mentioned.
