Sorry but I don't have any suggestions here but you say you have a lot of 454 blocks and cranks? Would you be willing to sell one? I have been looking for a 454 for a while. Like I said, sorry I wasn't any help, I just saw your comment and thought I might as well ask, thanks.www.streamlineautocare.com

Go find yourself one of those industrial 427s from the trucks. They all have forged cranks.

76 GMC thats what this 366 is,its out of a dump truck, and I'm not for sure what years they put the 427 tall blocks in the 2 ton trucks.

Yeah, your 366 crank will fit. I looked up some part numbers and the 366/396/402/427 all had the same part numbers for their cranks.

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
