Speaking of stroke...Keep the 318 block, add a cast 4.00" crank (now let's get that debate started...hahahahaha!) SCAT I beam rods, and a dish piston. You'd have a bolt together "little" 390-ish small block! The monetary difference will be minimal.
Power-to-price is probably the best way to go, except get a 360 block for as cheap as possible and stroke that which would result in a 408ci because the pistons for the 318 stroker are quite a bit more money than the 408, and also there are way more choices with the 408.. Im building a 396ci 318 stroker right now and the pistons alone were close to 450-500 bucks. To each is ones own I guess.
