Pulley issues!
Yep, thought I had it all sorted out. Nope. None of the pullies I have line up with each other. I have tracked my numbers and nothing is correct or matching to the parts catalog. Mismatched set of SBC pullies with a big block one thrown in. Anyone out there can confirm the exact and correct SBC, SWP pulley part numbers for the water pump, crank (including for the power steering) and PS pump itself? Need help and parts ASAP. Or what set did you buy instead?

Re: Pulley issues!
I *think* this is what I need per the Parts Book:
Crank - 3925525 (71-72 10-30 with power steering) Waterpump - 3995648 (70-72 PS with 62 Amp alt.) PS pump - 3925537 Can someone check my math?

Re: Pulley issues!
Thanks Dr. Jekyll! Helps a bit, I do have that cast pulley in my pile. I think I need 3925537 for the matching PS pump pulley. My WP pulley is completely off. Listed as 69 Camaro/Chevelle catalog part for a 6 cylinder. Dang thing almost hits the balancer. No way that is going to work!
