Hy Guys, the engine in this truck is a 366, that is a truck only engine, I have never seen a truck 366 or 427 truck engine with anything but a governor equipped Holley. Thousands of those trucks ran for years very well with that setup, possibly someone swapped a carb setup for a 427 or 454. Maybe we should try to identify what carb we are dealing with, before we suggest throwing it away.
