GM HEI how to buy. What to look for. What to avoid
I will make my way to the junk yards to look for a HEI ignition. I know what GM vehicle/engine to look for but don't know how to evaluate if it is good or not. How much play/wear is tolerable in shaft and components? rust? grease? Please help.
Nobody mentions GM V6, but will a v6 GM HEI work? example a 231ci or 2.8L from 78-85 year models? What is the difference with the drive gears and shaft?
