Thanks stock49, sounds like it took a lot of tinkering to get those carters tuned just right!
I am far from an expert, but I've seen that several people have had good experience with the dual weber 38 dgas set up from clifford performance...these are non progressive 2 barrels, with dual 38mm venturis and vacuum power valves.
Which makes me consider the holley 94...on the surface they seem similar, both are non progressive, both use power valves, and the 94 is smaller with roughly 25mm venturis...so if the weber works, I would think that with the right power valves the 94 should work as well...am I missing something?
