Damn, sounds like a lot of work and money. Carburetors work really well when you get them set up correctly. You did say it was "strictly a cruiser". Just add the HEI module, tune it and cruse.
a carb will never be spot on every day. too many variables. efi is constantly adjusting. last week here it was hot and himid, this week its cool and no humidity. no way a carb is dead on in both conditions.. efi on the other hand is.
