Finally got my new small block in the 67. Went to install my fan belts and noticed the pulleys do not line up. I reused my same brackets but installed aluminum pulleys.My 3 groove crank pulley sticks out 1/8"! I double checked to make sure my ati balancer was all the way in and it was.
I shimmed my alternator out. Then pulled the flange on my water pump out 1/8" That solved the inner groove. The middle groove will require some work on my a/c bracket. The outer crank groove (power steering) is actually a hair in.
At this point I dug up my old gm pulleys and double checked everything with straight edge and calipers. Turns out the new zoops forgelite pulley I got is the problem! Any body got the same problem with zoops?
straight edge is on the balancer side of pulley:
Looks like I may be reusing my old stuff, home summit takes it back.
Now I gotta press my water pump flange back in 1/8"! Do I need to remove the back cover and support shaft/impeller assy.? It is a stage 3 stewart components pump with a set screw on the flange that locks to shaft.
Thanks in advance, Ray
