By keeping the revs down to a resonable rate, I have not had a failure and I'm quite happy to leave it that way! The pump is able to maintain 25-6psi to the bearing and I belive it is the extra oil flowing through it that has made it able to last that long.
On some of our long outback trips, one of the guys who uses babbit takes along a rebabbited con rod and middle main bearing cap amongst his spares. I've seen him have to use them.

Okay, I of course believe you but as with almost all these types of comparisons on this forum what are we actually comparing? Are we comparing your quality insert conversion with a quality babbitt job; or rather, your quality insert conversion with a second or third rate babbitt job?
