Block casting number search

Bobzilla said
I think I have the same block you described. Mine also has just the R on the front, and an R, then space, then a 3 on the rear bell housing mounting area. Must be just a foundry number or something. Mine also has the Magnum engine mount bosses, and exact same casting number.

I'm going down to get some better pictures in the morning. I'll post them up when I get home.

If I keep the block I'm going to mill the magnum engine mounts off, and maybe the LA mounts and use an engine plate to mount it.

Maybe.
