I just had my rod journals ground and by mistake they also took the mains down to .30, I already had it ground to .10, bought babbitt bearings and shimmed it. I had the rod journals just polished tring to get buy cheap, then learned they were out of round, and had to send the crank back. My question is do I really need babbit mains or can I use regular mains? I see non babbit mains for sale, and to me they would be better. In a previous post you guys helped me with rod bearings and recommended getting my rods machined for inserts, if the scoops are adequate for lubing the rods wouldn't the low pressure system be enough for the mains? Thanks for any help, as you can see I am not to smart with this stuff.
