SB non AC crank pulley?
Yes a aluminum water pump, once I got that top pulley I got it all to work, I had to run the belt from water pump to crank to alt to fit, and the ps to crank, otherwise the crank pulley would not fit. I just measured OD for the belts. Thanks for the help.
Seems like their is a different in crank pulleys, BB to SB? maybe the PO installed a different crank pulley? I did a couple LA motors from scratch a couple years back and did not have this delima.
