I recently bought a 1978 T/A sport coupe.
Originally, it came with the 6.6l 400.
I was tearing it down for a rebuild but ran into some issues.
The engine is not a 400.
Heads are 4X, with a secondary stamp of 1H, and the front edge has #206318 YY. Ang G203
Block: #485428
So if I am deciding this right, it's a 1973 455CI with July 20 1973 heads.
I want to order the correct things. VIN# 2W87Z8L169478
