Carb Question

Why not give the 390 a try before swapping to an Eddy? A 273 shoudn't need that much carb.

Probably should, I'm bugged that they did not give me the jet size information for the primaries and secondaries. Just says it is set up for my engine-very generic. So I bought an air/fuel sensor so I can tune the engine. I expect commando+++ performance out of the motor build and everything I have read says these builds like 500-600 CFM properly tuned. If I put the Holley on, I know I will never take it off--------
