I'm currently building a mild 318 to replace a Slant 6 in my 1974 Plymouth Valiant, 4-door, which I got really cheap. After I picked up the 318, a friend mentioned the 360 as a better alternative, dollar VS output. As I have a 7 1/4 rear end, I don't want to blow up the rearend. BUT, the costs are nickel and diming me, where I'm at $1000 and still need a flywheel, possible clutch and exhaust. I could have picked up a running 360 from a guy I know, for $100!
