babbit tolerance? .000?

[mike657894]

What questions should be posed to the shop doing your babbit? What clearances are you going to hand me? Where do you get your babbit and what is its make up? Or brand name and type so I can research that? What other questions should be asked? Before I do a rebuild I try to do weeks of research and watch every method I can. And find all measurements that can be made to check for proper build. We have a good amount of information. But it pales in comparison to say the chevy sbc or honda rfvc singles.



Also I have seen the drill rigs for cutting it. Are those as trusted as an expensive align bore machine. My machine shop said he had a guy local he sent Babbitt to. And im thinking it may be a drill rig. I didn't know what to ask and he didn't offer further info.
