Thanks for the info, I never seen a cast iron crank pulley before and searched and found the power steering pulley was used on big blocks. I couldn’t hardly make out the crank pulley part number and figured someone here would know what combination it was for.

Looks exactly like the factory set-up on Otis.

Cast iron pulley looks like it’s been welded on.
You might want to find another one, just to be safe.

I think that’s dried oil from a past oil leak, I’ll look closer when I get home from work.

I have never seen cast crank pulleys on anything automotive. I would have assumed a marine application. Interesting.

No. Those cast pulleys were correct add on power steering pulleys for the 67-72 trucks.
I’ve had many of them.

I learned something else new about these trucks!

I had a cast pulley like that as part of a aftermarket AC system . It used one of those old York Compressors. The evaporator that hung under the dash was the size of a steamer trunk.

i thought the cast pulley looked funky too but it maybe just old oil,dirt and grease dried up but certainly it wouldn't be wise to use it,if it had been welded on.my big block 72 truck with factory A/C has 2 pulleys on the crank,both steel not cast.i have a couple cast crank pulleys here,i seem to recall they were on 62-64 283's or 327's in fullsize cars?

It was dried oil and dirt from a past oil leak.
