Note the larger air pump pulley.

The 1976 type 911/84 (California) is very similar to the 1975 type 911/44 (California).




The 1977 type 911/85 (for both 49-state and California).
Thermo reactor exhaust, 5-blade fan (1.8:1), air pump drive ratio 1.35:1, air pump pulley 138.5 mm, EGR, 157 hp.


The 1977 type 911/85 (for both 49-state and California) is identical (for practical purposes) to the 1976 type 911/84 (California).

Best,
