I'm replacing my 350 out of my 84 c20. I bought the Chevrolet Perfomance 350 HO. Went to swap over all of my acessories and I'm stopped by the crank pulley. The one I pulled off of the original is a 3 bolt and the new crate 350 needs a 4 bolt. I need the pulley in the next few days so is this just something I could pick up at the local Advanced or will I need to order one? Or could I just drill 4 holes and use the old one on the new motor? I know the pulleys can get complicated with different sizes and weights so I figured I'd come to the guys that know more than I do for this. Any help appreciated

Are you saying the balancer has provisions for a 4 bolt crank pulley? Post pictures.
