At the top right corner of my build sheet, under Engine, it says 8H. Does the H mean an HO or anything special? The engine block has a WZ on it though. The Vin number has a 0R as the engine type.

The VIn # is 22437-L0R-3..... I know the L means built in Van Nuys. But what does the 0R (that's zero R)?

Thanks Firebird fans

WZ is a manual trans 400 engine code. LOR= Lordstown

LOS = Van Nuys

Also Van Nuys vin plate has an "L" and Lordstown has a "U."
