I have what I think is a 292.  It came out of a 64 truck.  The block number is EDB with D.Mummerts info site does'nt list this number (the D part).  The pistons are stamped .030 and measure 3.805.  The stroke is 3.30".  The mains and rods are marked EBU.  Rods measure 2.17" and are not marked as to size.  Mains measure 2.534" and are marked .010.  The crank flange has a half moon notch and no dots.  The rear main cap appears to be slightly shorter than the others.  I know the 312 used taller main caps on all except the rear main, but how much taller?  The heads are C1TE.

Thanks
