dgc333. thanks a lot for the tip, that helps a lot and like i said the majority will be street driven with a little fun track time so i think i'll go for the 650. thanks again


dougie800, thanks for the tip, i wish i had more to spend on a carb. but unfortunaly i'm on a fairly strict budget.

I think a 650 Edelbrock AVS is a good choice; the adjustable secondary air door will allow you to fine-tune it more as you upgrade the engine. I've ran an Edelbrock 600 AFB on my 318 and it worked great (even got 1.5-2 MPG better than my ThermoQuad). ThermoQuads are great too but you'll need to do a LOT of tuning to get one to run any better than a "new" Edelbrock, and you'll probably have to re-do all of the jetting and settings on the carb once you add a cam and other stuff.
