Finally got a 4.2 shortblock. I'm at the point now where I am going to do everything while I have it tore apart, transmission and rear end included. As far as the engine, I was thinking of putting in forged pistons, and a cam. I was thinking about Morana for the pistons, and rpm mustang for the cam, but what does everyone think? Is Morana cheaper? I'll be putting my vortech on it, which turned out to be fine. Injector size, throttle body, and any thing else?
