Your Welcome Charles...

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.
