Update: 11/8/10

Got it tore down today.
Bore is .040 with a good cross hatch still showing.

Pistons. Decompression type maybe 12cc dish. CAST

Steel crank. .010/.010. Rod and main bearings look very good.

Cam. Unknown, No #'s of any kind of markings on it.

Heads. Like I said 461's. 1 ex valve is sitting ALOT lower in the head than the others, Does not look like any hardened seats have been installed.

All in all I think it may be a good project for a later date or it may become trade fodder.
