the 74 chassie had a 350 in it, are the newer motors mounts the same as the older V8's? i would put the 4 bolt 350 back in but i built it into a monster small block and it was sold back yrs ago in my 69 camaro, back in my 20's lol sold it to buy my beach house. hated to and i also sold my 62 chevy truck at the same time for the beach place.
