I just bought a 94 LT1, 6 speed that needed an opti and water pump. I had an opti and water pump from a 93 engine with only 21K miles on them. Installed these and the car ran great. As I was installing the serpentine belt, I noticed the compressor pulley was frozen. So, I have a compressor from the 93 engine...only 21K miles but different part numbers. The compressors look close to the same, but not exactly. The 93 P/N is 1136055 The P/N on the 94 is 1136077. Hollander says that the 1136055 with fit 93 Camaro/Firebird with 5.7 engine and 94 Camaro/Firebird with 5.7 automatic. 1136077 will fit 93-96 Camaro/Firebird, Caprice/Roadmaster with 3.4, 4.3, and 5.7. In 1994 only, the 1136055 was used on the automatic LT1's and the 1136077 was used on the 6 spd LT1's and others.

Anyway, I probably repeated myself a time or two, but can anybody tell me what the difference is between the two compressors, and if I can use the 1136055 in place of the 1136077? I checked at a parts store and they listed 2 compressors for 94...1136077 was $219 reman, and 1136055 was almost $400 reman.

I know I can bolt the compressor on, but don't know if the lines will hook up to the back or if the wiring will work.

Any help would be greatly appreciated.

Thanks,

Paul
