Tweet

whats the norm here... i have one going to tegether and im over .004 clearance at the mains and rods? too me that didnt seem right...help me out here..

yes it is not you need to watch your oil clearancen that much you will have i hard time keeping a oil flim on any thing how did you check it out with

plasty gauge... an double checked with mics....
the rods are around 2.1975 too 2.1955. with standard bearing coated(king)

and about the same with the mains. .0043 too .0048 at the thrust. i planned on running around .002 too .0025 standard volume standard pressure pump setup.

i thought i told him to have it turned and polised in, but they just polished it..

this is not good. or should i just suck it up and put a high volume/ high pressure pump in? IMO its too much. can i pick you brain on the phone pm me a number if you could...

yes you can

thanks pat..

great info
