I'll stand corrected on this point, I could have sworn I read (from a reputable source) that the 2280 was a later factory part but for the life of me I can't find my source to back it up now. So I will defer to Dan's wealth of knowledge here.
Regardless, if Dan says the 2280 is a good carb, then perhaps I just had bad luck with the example that came with my intake. I was never able to get the engine running with that Holley.
With the Weber 32/36 I have had a substantially better experience and more recently I've been talking directly with the people at Redline (USA distributor for Weber). There own advice was to get a 38/38 for this size of engine. The 38/38 and the 32/36 share the same bolting surface, which is why I know with an adapter plate either will fit the super six intake.
