if you google "image 1967 Chevelle SS engine" you will get lots of pictures of AC equipped engines. You could also try looking in a copy of the 1967 Chevrolet Chassis Service manual. Do you have the correct short style water pump? http://chevellestuff.net/qd/water_pumps.htm
yep, correct pump is on it, low mileage car (55k) which i've owned 7-8 years. why the belt doesn't run true is the mystery.i have the service manuals but didn't look in there-great idea. last spring the compressor clutch died and the replacement is identical but the belt angle is too far back or too far forward. we thought the brackets might be wrong?
