56 Water pump pulley???

[Ken J.]

Can someone tell me what water pump pulley would be on a 56 240 H.P.
Spec, Cam engine. Is it the tapered one or the stepped one. I know the hi performance engines in later years used the stepped one. The other pulleys are deep groove on this car.
Thanks in advance for any help given.

The pulley was GM #3704172. That number should be on the pulley.

Is the 3704172 pulley tapered or stepped? Is the deep groove type?
Thanks.

I believe it's of a stepped design.
