its a 97 350 out of a 1 ton, it has a spun rod bearing, I want to stroke it to 383 put on a intake manifold and a carb. is this possible with these newer generation block. or should I buy an older one and just keep the heads? I'd like to build it up to about 400 hp 450 tqe. I really don't know Jack about engines but I'll learn. I want to build it strong enough to handle a little NOS too, anyone know of any good 383 info on the net?
