I have a stage II off center block, alluminum heads, Isky cam, buick motorsport crank, roller rockers and a bunch of other parts but I am new to the game and have been told that if I want A\C I can't use what I have I thought about going to a T\A performance alluminum block but I wont if I don't have to. If anyone can help me get this motor together I would greatly appreciate it. There is a guy I work with who runs a fox body mustang that I would like to shut up.
