I'm trying to get my A/C back up and running. I've replaced everything, its all new. However I'm having problems with the belts. My motor is a 350 out of a 1980-85 Chevy truck. I've done some research and it seems that the stock 305 in my TA which I never saw nor do I have came with a 3 groove crank pulley. Is this true? I've eliminated the air pump so no need for a 3 groove water pump pulley. Can someone chime in with some advice or possible picture of the factory v-belt set up?

 

 

Hey Marc,

Nice to see you in Atlanta! So in that bottom picture, looks like you need a long belt that goes around the A/C, Water Pump, Crank & P/S as well as a second belt around the crank and P/S. Looks like you will need a 3-groove pulley for that larger outer belt. I used the pulleys off my 305 on the 327 and the crank pulley is a 3-groove and I too had A/C, Air Pump at one time!

 

Thanks Bryan, on the hunt for a 3 groove pulley. I may have a line on one tomorrow. Have a good evening buddy.
