2 with 113 heads, 1 C2AE with a 4spd truck bell and tranny - maybe forged crank, and one that is probably 239 or 256 - has core plugs in the heads and dual exhaust manifolds.  I'm thinking I'm going to get them all.  Don't know where I'll put them, though.  There were two trucks that had the engines pulled but the bellhousings were there - both 4spd.  I might get them, too.

I think I'm officially addicted.
