crank pulley
On my Brothers Blazer, the crank pulley is 2 piece. The alt/water pump crank belt is flush against the dampner. Then there is a cast pulley that bolts to it and sit about 3 inches from the dampner that the power steering pump uses.
Is this stock? It all looks original, but no telling what has been done to it since it was new. It is a 4X4 70 blazer V8 short water pump. Hope you can see what I am describing in the pic.

I am currently dealing with pulley issues and I have not seen that one but I have not looked at Blazers. The crank pulley is probably the equivilent to my 4-groove pulley plus I have a 3-groove WP pulley. Does the power steering pulley have a flat or concave back side? The flat back is a BB pulley and the concave back is a SB pulley. I am guessing this is a non-AC truck.

It looks like the original setup to me. 69-70 were the same and used cast pulleys.

Pulley
Ditto on the 69-70. In my experience with pulleys, if it lines up and the belt stays on LEAVE IT ALONE.
