But the invoice doesn't list untized ignition.

The 2 VIN's we are bouncing around are 7789 units apart.
Maybe the engine is a coincidental replacement that just happened to be really close in relationship to the parameters.
We might find out

72 formula 455 had mandatory unitized blocks so WM only on a 4spd.

72 T/A could be either way WD or WM by the way it was ordered.

Saying that, I'm not sure if unitized would show up as a charged item on a Formula on invoice separate or was it part of the charge for both "Ram Air" and "unitized".
