Sanden A/C Compressor to fit a 273
As somebody who has PS and AC and headers on a 273 in an early a body with the factory cast iron water pump the classic auto air brackets for a 318 be prepared for cutting and modifying ALOT! Best to do this on a stand and 360 degree views to keep the pulleys aligned so you don’t throw belts.
You need to make a lot of spacers and most of the bolts in the kit don’t fit the cast water pump. If you swap over to the aluminum water pump then the front cover needs to be swapped along with the proper pulleys. It can be done. Just be patient and take your time.
