SD-455 pistons do not use an offset pin. Yes, they have a single complete cut for valve clearance. The rods do have a proper facing ID mark on them . I am refurbishing a stock engine right now. The cold noise maker were the clunky, heavy TRW forgings, the large piston to wall clearance specified, .006"-.0068" factory spec., and the high growth 2618 alloy used to forge them. Personally, I love the sound. Like a well tuned diesel until they warm to operating temperature. No doubt there is an SD-455 under the hood when one starts up cold.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
