The only skinny block six I've done is a 292 into a 57 1/2T. I allowed one day to mount the engine in place and hook up everything but the exhaust---big mistake because it's not a quickie swap. Have done one other old six to new six in a TF but it was the much superior 300 Ford into a 56 GMC. The owner of the GMC will have to die before he parts with his truck. One other footnote; neither one can pass a gas station.
