O.K. Here We Go...... I'm going to make multiple posts with many photos so give me about a 1/2 Hour to Finish.

First off is the 1971 455 Block Cast #485428 with a Date Code of B221.

It's unusual due to the Casting. It actually looks very much like a 1970 Cast #9799140 without the Two Outer Bolt Holes for Four Bolt Main. This Block is now Drilled and Tapped for 7/16" "Splayed Cap" Outer Bolt Holes.











More to Come,
