Well, it took me a bit longer to get to work on the subaru than I thought it would, but that always happens. After we got done with that car, we pulled the flywheel off the big block (which took a little over a half an hour...that thing was on there SOLID). On the crank flange, there was a big "C" shape cut out.

I imagine I can safely say that what I have was originally a 425 block, but when it was rebuilt it had 455 rods, pistons, and either a forged crank, which I hear was the best kind, or a plain jane cast iron crank. The guy I bought it from said it was a monster of an engine, and it tore 2nd gear out of one of his TH-400 trannies, so I'm thinking this engine may be cammed up and/or bored out as well.

We're getting it off the homemade engine stand contraption that it's sitting on sometime soon and putting it on a real engine stand, at which time I'll pull off the oil pan and figure out exactly which of those cranks I have.

Anyways, I'll keep progress on this car posted.
