It's even a little more complicated than that.
The BJ8 block is different from the earlier 3000 type in that it has the
dip stick in a different position and I'm told improved internal gusseting,
although I have  ever actually compared the 2 types.
Boring a 100/6 block to 3000 can be done but is *VERY* risky as detailed
here.

Hank, I'm very interested to know if you have any experience with line
boring a Healey 6 cylinder engine in order to accommodate mismatched main
bearing caps.
I approached a very experienced shop that I have great confidence in with
this issue and was told that to do the job "correctly " involved an
extensive amount of work as in the case of the particular engine I was
trying to rebuild the center of the bore on the caps was displaced around
0.018" from that of the block.
