Had a guy ring me chasing a bottom pulley for Y block .He needs a double  groove add-on for A/C.( He wants to run A/C seperate form P/S .) Why ? I don't know ?

Question ?? Are they available ??? Where from ??

Lon:

Frank's supercharger pulley with dual grooves would bolt to the front of the stock one and give a total of 3 grooves.  Is that what he wants?  I don't think the factory made any like that except for the supercharger pulleys.

Thanks John . Thats what I wanted to hear .Yes ,he wants 3 grooves . Alt ,P/S & A/C all on seperate belts .I don't know why  either ???? There are a few places that sell A/C & Alt brackets kits to suit Y blocks . I suppose it's his car and his money after all .

I have a similar problem with my setup. I have an after market A/C setup from a 57 T-Bird. With my pulley setup and the wide belt for the supercharger, the only option I saw was a 60" long belt to drive the power steering, water pump and A/C. Looked like it might work with an idler pulley on the longest leg but the angle over the water pump was pretty flat.(about 20Deg down angle on each side) I don't know if I can run a multiple groove damper with the McCullouch pulley without getting into a lot of alignment problems. Any Ideas? Chuck in NH

Just fix the windows so they'll roll down and throw the A/C out.

Moonshadow's car must be from the South.  Didn't know they knew what AC was in NH.

Actually my car was from El Paso! I just get tired of the 2-40 A/C. (2 vent windows at 40 MPH). We rarely need A/C up here but I would like to have it. Must be a left over from my midwest upbringing! Wink Chuck in NH

Check out Ebay listing item #380114294671.

The Ebay ad item number that’s listed is for a waterpump pulley but two groove accessory pulleys that bolt to the front of the damper do show up occaisionally.  Here’s a picture of a two groove accessory pulley and also a picture of a factory 312 damper with three belt grooves.

I would like to try the add on two belt pulley someday. But I would have to add the McCullouch pulley onto the front of that! I guess all the alignment could be fixed. Chuck in NH
