Re: 68 427/400 Fan Clutch Causing Vapor Lock?
My old Orange 454 Suburban had the fan clutch from hell. There was no doubt when it was working -- it sounded like a B-29 taking off. And yes I AM old enough to have heard a B-29 take off. If I left it idling with the front & rear AC on the fan clutch would cycle on and off -- and when on you couldn't carry on a conversation in normal tones within ten feet of the truck. It was comforting to know it was working.
