I've heard pros and cons about both the Bi and Tri metal bearings for the mains and rods. What is everybody here using on there rebuilds? TR3 engine. Also are all the Dimensions and Tolerancas for the TR3 TR4 engine the same except for the pistons and liners?

I've got some tri-metal ones squirreled away that I'll be using. But the bimetal are good enough, IMO, I'd use them if they were the only thing available (which is sometimes true).

I went with King tri-metal bearings from BPNW and the machine shop that did my engine said they were great quality.

Thanks guys, I used the tri metal in my TR6 and all is good. I just wanted to make sure. I also will order mine from BPMW.
