I am using ACL mains and King trimetal big ends and so far nothing has
exploded after a few hours dyno running. The colour of the bearings is an
indicator of whether the Kings are bi or tri metal- dull grey as opposed to
light aluminium colour for the bi-metal from memory.
The King bearings had
quite a number of small lumps on both the back and front faces which I gently
scraped off and smoothed with 1500 grit sandpaper before installation. The
ACL's went straight in.
More important than the manufacture of the bearing is
the clearance and I'd strongly recommend determining the installed bearing
diameters before grinding the crank. Mine were all on the bigger side of ok so
the crank journals are ground between 0.06 and 1.00 thou bigger than the max
book spec to compensate.
