Find a 360. I don't care what you do to a 318 you will be disappointed after you waste all that money on it. They were never. Made to be a performance engine. Sorry if I ruffled anybody's feathers.
I guess the 290 hp, that my MILDLY built 318, puts to the ground is a turd. 8.86 to 1 compression, cam 210/[email protected]. 3800 lb race weight and ran a 13.27.
