1986 - 1987 SBC Alu Pulleys - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for where you can find aluminum pulleys (crank, water pump, and alt) for 1986 and 1987 SBC that use the original type of belt. Below are pictures of my pulleys and belt. Who sells these things?

Thanks,
Les

The belt for crank, water pump, and alternator.

March makes them. But they will be Spendy. I have a 50% under drive crank pulley on mine and regular steel water pump and alt pulley. Serpentine like yours.

I have a set of Mr.Gasket underdrive pulleys for a Monte Carlo. I think they are the same pulley. PM me if you're interested

I actually converted mine 86 to all V-grove when I added AC. It was much easier to deal with getting everything to work and plenty of aluminum pulleys where available.

GM actually makes a kit to conversion kit to convert everything to serpentine but it is very expensive and includes alternator/water/power steering pump. PN is 12497697. $$
