Well i just got my alternator cleaned up and mounted today, along with my water pump pulley, balancer, and crank shaft pulley. i think the balancer is the original one to my L30 engine sitting in the garage, the crank shaft pulley is one my dad grabbed from the garage, it might be a big block one? it fit the balancer so i assumed it would work. does the balancer need to go on more? there is a gap between part of the balancer and the timing cover seal. I put the balancer on with a crank shaft bolt, the bolt either bottomed out or the balancer is on all the way. also is my water pump pulley an original? is it a big block pulley? I found one that is for a bb camaro on google images. thank you:thumbsup:
