Hi Guy, I have just finished reading the other responses and agree with them
all. Two more things to check, 1 are the bearing caps in the correct
orientation ie: the caps must be installed from whence they came and make sure
they are not 180 deg out. My buddy and I had a similar problem many years ago
and it turned out that the PO had marked the con-rods 1,2,3,4 and the
associated caps 4,3,2,1. As you can imagine it took many hours of trial and
error to figure out. This of course was on the big end journals but the same
may apply to your mains. 2 have you checked the end float, as the thrust
bearings may be oversized.
Hope this helps.

Subject: Bearings - how tight should they be?
OK, I've got my re-bored 1275 block and reground (-0.010) crank back from
the engineer's shop.
Assembled crank into block, without the pistons as yet, so I am only
dealing with 3 main bearings.
The crank is tight. Not so tight that I can't move it, but it certainly
dosn't "spin" Should it ?
I can just rotate it by hand -- two hands that is, but it takes a lot of
force.
It turns smoothly with a bar as a lever between the flywheel/ crank bolts.
No high spots, but just stiff.
Does that sound right to those who have done this job before, or should I
scrape the bearing shells?
Guy
