Hey Windsweptfiero, I like your priorities.
I ordered the Holley 2300 rebuild from Holley. It came jetted, shootered, and cammed ready for a 350 sbc.
Mine is the 350 cfm, little brother to yours.
You probably will have a carb there that will handle 350hp nicely. The Holley is a flat track racing carb and is set up fairly aggressively. The rebuilds no longer have choke and I had to salvage a butterfly assembly off a dead 4160.
The guy to ask though for your 4.9 is Mastertuner Akimoto. He knows this subject backwards and forwards.
Good luck. BTW, Coming to the Grand Bend Cruise across the Blue Water?
Edit - I'm using an after market Corvette style (also Moroso style) 14" aircleaner with a sixpack scoop
