I am swapping out my 289 for a 5.0 out of a 95 gt. I am running into a problem with my pullies. I am using the 289 timing cover and waterpump. The 95 balancer is too far out and has a 4 bolt pulley. My 289 has a 3 bolt crank pulley. Do I just buy a 50oz balancer and go? Or is there more? I am using the 95 flywheel also.
