Most of the guys around Texas seem to run the Indy "crossram" intake, although the two AFBs are almost inline. This is both the Hemi version as well as the wedge (440-25). There was a guy from Division 1 running the Indy crossram (426-8) on his SS/E RO Plymouth and he set a record with that car, so the Hemi intake must work pretty well.

I'd get another 800 AVS since you already have one. I think most of the guys are using the AFB version, but I haven't looked that close at the carbs. Chuck Beach runs an AVS on his 340 Stocker and supposedly makes his own accerator pump piston to make it launch. That may be something to play with?
