Yeah thanks, going for a race spec

Yeah thanks Brian, just musn't be much call for them and they've stopped manufacturing. My old crank was 10under and polished so not a problem but it's now a two piece crank and not working so well!

agreed, street and race are totally different requirements, I'm running 7200rpm and 14-1 compression, like you say you'll definitely spin a bearing with standard clearance. These old girls aren't manufactured to the tolerance of the new gen engines that will live with tighter clearances

Thanks but they only list standard size

Can anyone advise a manufacturer and part number for a standard 440 crank .001" extra clearance main bearing. I can't find one , my current clearance is only.0015" and I want .0025"
