I need alittle pulley help??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is this a bb or small block pulley. I was asked if the three holes makes it a bb pulley also. Any help is appreciated. Thanks Randy

I'm pretty sure small block pulleys have three holes also.

That looks like my long water pump lower pulley. outer,alt middle p/s inner a/c I guess it could still be bb or sb.

I almost swear I took them off two 69's which were small blocks. All my BB stuff, I sold in package deals, Thats why I think they are small block. Thanks Randy

It is for a small block, BBC pullies have a larger center hole. I also suspect it is for a later model due to the different sized pullies as an integrated unit. On our trucks the power steering driver pully was added to the stack as an add on.

I don't know guys, it looks alot like the one I took of my big block. But who's to say somebody didn't put a small block pully on the motor befor I bought it...

The question was asked to solve my problem. Thanks teeitup and the rest of you. I got it to work. I just had to bolt it up on the outside of my existing crank pulley and it worked great.

I see four holes ......lol

(just kidding)

In my opinion they all have 3 (bolt) holes SB or BB
