Hah, bumping my own thread now. I've been reading some other turbo threads and found Tower saying the Holley 600cfm double pumper (4776) is better than the 500 because it's more drivable when not in boost and it's easier to tune. From a few quick queries, it's more available and just as cheap. Plus, no need to get an adapter plate for the offy. Should I stick with the 500 or is the 600 a better overall carb for me?
