I've thought about running copper lines instead of the heater hose, but haven't gotten around to it yet.

Hey Brad, I like your clutch rod. Looks familiar.
Dave -- I used to run the 390 Holley on a .030-over 292 with Offenhauser intake and Clifford headers. It lasted about 25 years. But when I rebuilt, the Holley wouldn't set up any more, so I got an Edelbrock 1404. The 2005 build was the original '68 292 block, also bored .030 over, but with bigger intake valves, Crane 260H cam and the same intake and headers.
Carter used to make a 400 CFM version of the AFB carb, but when Edelbrock took over marketing of this style carb, the smallest CFM 'Performer' they sell is the 500. Don't be afraid of the numbers. The secondary valve system is a demand type design. It flows only as much fuel/air as the engine vacuum demands.
Personally, I prefer the Carter/Edelbrock design for its ease of tuning and rebuilding. Holleys are great when set up right, but I'm no rocket scientist.
