I've looked for one of those "small bell 400" blocks for years, never seen one.  A long while back I spent an entire Saturday in the big wrecking yard here, looked at 45 cars with 400s.  Not a single SBF style unit. Note that IIRC, 400 blocks in the years before 77 had a valley cracking problem.  So finding a SBF 400 may not be the holy grail you might think.  Easier to find a C4 (C5?) from a 78, 79 T-bird with a 351M that had the 341M/400/429/460 bell patterns to pan fill C4.  I think the door plate trans code is "X".  I have two of those.  Except for that oddball 400, all 351M/400s use the "460" bell pattern. Also - it's easy enough to buy a JW adapter bell to go from the 460 pattern to a C4 and such.

Well, got some follow-up news, but unfortunately not good news.

My buddy got new bearings rolled in the Tunnel Port, so I rolled down this morning to go help on the dyno. 

First lick out of the gate was 610 hp @ 6500.   We didn't know much about the combination since someone just brought the engine to my buddy's shop to dyno, so we started out conservatively at 38° timing.  It showed on the plug that it wanted a little more, so we gave it 41 (from my experience, the TP engines like 40-42°).  It dropped 10 hp and then when we put the timing back to where it was, it lost 10 more.  That's usually a tell-tale sign of bearing issues, so we shut it down before it did something bad.  Cut the filter open and there was copper all in it, so that's that.
