Here is a 273 belt system for a 67 with AC and power steering. There are only 3 grooves in the crank pulley

Yeah the 4 groove threw me off, our 273 did have ac, ps and its 3 grooves.

My 65 also uses a 4 groove crank pulley.

Thanks for posting, I wonder why the AC compressor has 2 grooves? Early A, 66 and older maybe?

Is this crank different than the one on a 318? The system for the 318 is much simpler after the change to an aluminum water pump (1970) because the switch to passenger side lower radiator hose meant a much lower PS pump. 2 belts alt & AC, 1 for water pump and PS pump.

Still looking for the 1965 273 4 groove crank pulley, and idler for waterpump to crank. Thank you

I have a 4 grove pulley I think it’s off of a 360 not sure here’s some pictures

273 is a different pulley with a rubber damper built in and different diameters. But thank you Del, I appreciate it

Yeah it’s unique for early A with AC. I may have one, I don’t recall what I kept vs what I tossed. I’ll look tomorrow.

Sorry I looked on the shelves, on the scrap pile, and in the shed and I can’t find that pulley set.

Thanks for looking Moper

So I was in another shelf of early a stuff and found this… I owned (2) ‘65 barracudas. One is a slant car, one was a 273 with power steering and dealer added AC. This pulley is cast iron, not formed steel. I thought it was used in addition to the single groove stamped steel pulley. That’s how I remember it anyway, but this pulley has red engine Paine on it, which means at some point early in production this went right onto the balancer. I can’t find the single groove stamped pulley…
I also have a customer with a ‘65 Dart GT, 273, ps, no ac. That car has a factory pulley with cast iron and rubber. So I’m not sure if what I own would work, or if you need the factory one with rubber.
But I have this if it would work for you.
