Dave, correct me if I'm wrong, but the code numbers on that page are not casting numbers, they're the grind number, right? I THINK different grinds were applied to the same casting numbers and potentially multiple different castings were used for similar grinds, so the key is to look at the number inscribed on the 3rd bearing journal, right? I'm sure that's what you're referring to, and I'm being pedantic calling out the distinction between casting numbers and inscribed numbers, but I just want to be sure.
The FSM describes a 2 digit code, but in reality the code is 3 or 4 digits, and the first two are the "code." Subsequent digits I assume are revisions or lots.
My 94 cams have the following inscribed numbers:
R intake: 980
L intake: 960
R exhaust: 023
L exhaust: 000
My 95 cams have these:
R intake: 983
L intake: 963X
R exhaust: 023
L exhaust: 001
I don't know what the exact 3 or 4 digit code would be on the 92 cams, since I assume multiple distinct codes could apply, but I believe they'd be 72* and 74*.
