Actually the SD's ended up with the Pontiac "Y" camshaft. It was essentially the 744 cam with the smaller distributor gear. Not one of Pontiac's greatest efforts IMO, but a decent camshaft. Little lumpy idle. Could use some more lift, even with stock heads. Because of the car's value and probably limited use, I am probably going to just use that cam. I have an NOS one. SD cam cores are hard to find because of the small cam gear. I am sure my friend Tim Goolsby at Ultradyne/Bullet could grind a flat tappet cam that would be just as smooth and make 25-30 more HP. But I am leaning toward leaving this one very stock. It's a delicate trade-off when dealing with a more rare car/engine.
Johnta1: I do have the PHS. It is also in the SD TA registry. It has the standard black interior. It was sold in OH to a smaller northern dealership. Too many pages to post, but happy to supply specific info of interest. It's a Norwood car.
