Restoration / small block pulleys
« on: March 27, 2008, 06:46:34 PM »
I have a 69 RS with 350 in it.
I bought the 69 Z-28 deep groove pulleys for crankshaft, water pump, power steering and alternator. I thought all would just bolt on my 350 motor without problem, but I found that the 2 groove crank pulley sticks out about 3/8" too far for belts to line up. apparently the crank pulley for a 302 is different than the crank pulley for a 350, am I correct??
Also I was under the impression that from 69 and later, ALL pulleys were deep groove, is that true or false??
If that is true, Why are people like myself spending money for the Z-28 Deep Groove pulleys???
And if I buy yet another crank pulley for a 350, will I be able to mate it with the Z-28 pulleys I'm using now?
Thanks guys, first time on this site.
