I've successfully had a block align bored, but the shop did the job right.
All blocks have trust bearings--you shouldn't have to tell them how to
suck eggs. I'd take it back to the people who did the work. You might also
want to add a strongback to the center bearing while you're at it.

Subject: center cap thrust woes
Amici,
In my continuing quest to make my life harder, and not waste any orphaned
TR parts, I chose to use a spare TR3 block that was donated to my cause
without bearing caps to build my new TR4 engine. I took my spare main
bearing caps that I somehow collected to the only machine shop in town
that line hones and they picked out a suitable trio of caps and line honed
the assembly. Unfortunately I didn't specify that they should watch out
for the thrust surfaces and they do not line up. My new machinist suggests
that the center cap is held in by clamping force and by being pulled into
place. He thinks that with a slight increase in the size of the bolt holes
that he can get the mess aligned. If need be he suggested that he could
drill into the cap/block edge and pin the cap in place if need be. The
question is, is that needed? Is this a good idea at all, or should I go
back to the line bore shop and tell them to fix it? TIA
