M60 seems conspicuosly absent. Am I missing it?

[shogun]

How do you tell which material is in your short block ? That part is fairly easy. But it requires getting under the right front of the car. All M60 and M62 blocks have casting numbers on the right side, directly alongside the 3rd cylinder, slightly above the coolant drain bolt.

These are the casting numbers to look for:

Nikasil M60B30 1 725 970 or 1 741 212
Nikasil M60B40 1 725 963 or 1 742 998
Alusil M60B30 1 745 871
Alusil M60B40 1 745 872
Alusil M62B44 1 745 873


NOTE, all US market M62 engines are Alusil.
