318 Pulley alignment issue...

Scrap that, I had it backwards. I might have a 318 balancer if you need it. From a 74 teener. Pulleys, I don’t know. I had a similar problem on a stroker I built. I got a wp pulley spacer and cut pieces of a jack handle to space the alt, one of them small one tons, and it lines up great in an a-100. Are you using the 360 or 318 flywheel/flex plate? Quite sure it has a weight on it for the 360. I also noticed the pulley is too far forward, not back. Sorry that didnt help either.
