I used a citrus type of jell paint remover, let it sit. I got old carpet and layered under the engine compartment. got a hand pump sprayer filled it with hot water and pressurized it. Sprayed off the jell....got my air compressor and blew off the motor to semi-dry it. Then I got my angle air die grinder with a wire brush attachment and went to town. then repeated the process. I did use brake cleaner,carb cleaner..anything to cut the old paint. When I was done I turned up the heater in the shop and dried the motor real good,primed with motor primer and then used GM engine blue. I believe it turned out good. It was not a weekend job, took my time.
