Joe....that's a purty balancer 

Ok, based on that pic i would have to say that your engine is internally balanced (forged crank) and has the standard 440 LY rods with casting number 535. The heavier 6-pack rotating assemblies we talked about via PM use a different balancer with a scalloped weight welded onto the front. I'll include a pic of the 6-pack balancer so you can see the difference. 

It also looks like there is an aftermarket oilpan on your motor so it's quite possible that some parts have been changed over the course of time.
