Crankshaft Play
I pulled my 272 out of my 57 truck to fix the rear seal very small leak and paint the engine. I pulled the harmonic balancer and notice that there is play in the crankshaft front to back. I'm not an experienced engine guy, so should there be any play and if so how much? What would be causing the problem a bearing?

Are you SURE it is the crank and not the balancer that is moving?
The balancer is 2 sections seperated by rubber. That rubber is well known to break down and cause the 2 steel pieces to move independently. This is also a major cause of Y block timing problems.
