Hi guys, i am in the process of paying off a forged shortblock and i have a couple questions. I originally told the shop to make a forged bottom end for a 2 valve but i decided i wanted 4 valve. i know theyre the same block but im wondering since its just a shortblock and nothing else would it be an easy change or would it need machine work? and i also wanted to know if it is just a straight through change to 4 valve how much is a whole terminator top end or a stock 4V top end from other years and models that can fit the terminator blower like a navigator? if its not a straight through change then what could i do to get a lightning supercharger and manifold?
