It doesn't make sense to me to buy a 360, what's wrong with using what someone already has. For what I'm wanting to do with it a 318 should be more than enough. Let's see what someone finds wrong with this combo, 600 carburetor, performer intake, headers, 2 1/4" mandrel bent exhaust system, 3.55 gears, 1,800-2 400 stall speed converter. Howard's 255 / 261 cam. Cylinder heads ?
