273????

A good valve job and some mild port work & gasket match works well with the little 273 heads. You can use either the Edelbrock or Carter 500cfm version carb they are about the same. I think Holley is even making a smaller version 4bbl now. Check Summit & Jegs's catalogs. I wish I still had the specs on the Commando 273/ Charger 273 HI-PO cam, that might help in picking out a new cam. If I can find'em I'll post'em.
