I was wondering if anyone could supply me with the correct pulley numbers. I have the 71 assembly manual but the car is a 1972 model so there might be some differences. the engine is a 350 5.7 naturally aspirated 4BBL, with Power steering and A/C The A/C compressor is on the passenger side and Alternator on the driver's side. The car was actually assembled 8/71 based on the door tag in Lansing. My 71 manual has the crank pulley as 399405KC and the Water pulley as 407534KK. the power steering pulley in the manual is 399406KH. Would these part numbers also carry over to the 72 models. The pulleys on the car all seem to be deep grooved. If someone could supply me with a photo from a 72 Assembly manual or correct numbers that would be great. I'm buying some extra pulleys from a friend so that I can have them powder coated for a later install, but want to keep everything stock. Thank you !

 

Here are the 1971 pulley part numbers. There should be no difference for 1972.

 

Here are the pulleys for the 72 350. They do have different part numbers and codes from 71. I would guess the 71 pulleys would work as the 2 years share the same water pumps.

Huh so if I had HD cooling w no AC the car would have a 3 groove crank pulley w 1 unused groove

 

Mr. Shifty thanks for the 72 numbers ! My friend had mentioned that he thought the numbers were different between 71 and 72 might be different The power steering number is the same but the Crank pulley is a different number along with the water pump number.
