About the main bearing grooves, I thought like George that 360 ° was a good thing, but I read in the Clevite catalog a whole text that explains that a 180 ° groove is the best solution.....?????!!!!!!


I've also seen the ACL bearings that have a 270 ° groove and claim that it's better than 180 °, so they contradict the Clevite theory and it seems to me that it's a good compromise between the lubrication of the rods and the load capacity, even if on a V-engine the maximum load is not directed downwards. They also exist in +0.001 ''

What do you think
