Is there any difference is the block between a 340 and 360 aside from bore? I was looking into swapping my 318 out for a stroker or stroking it, but didn't know what all the blocks would handle. I assume the 318 bottom end won't really like holding up to 400+ horse or is it 4 bolt mains? Would there really be any difference bottom end between a 340 and 360 or will they both take power equally well? I expect a blower to go on top at some point, but that's a fair deal in the future.
