So, where does that leave us?

I didn't plan to spend My ENTIRE Saturday doing that, but what the Heck... I'll tell you Guys what I'm going to use for My Next (Personal) "Stock Block" Performance Build. A Late 1971 to Late 1974 #481988 400 2-Bolt, 2-Bbl. (No Cylinder Bore Chamfers), with Splayed Caps on the Center Three and 7/16" Fasteners on the Outer Bolt Position. This Block is Very Similar to the (1972) Cast #485428 455 Block that I Illustrated. (Now I've got to find one with sufficient Cylinder Wall Thickness.) "Screaming Chief" shows what this Block looks like in His Posts #171 and #172. (Thanks for Showing that 1977/78 Block with the 1974 Casting. I was Totally Unaware of that. Once again showing that there are No "Set Rules" Pertaining to Casting Numbers and Date Codes.) Have a Good One, Larry S.

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.
