Hi all,
I know it's not a 300......same engine......probably better here than anywhere else for this specific engine.
N/A, not a performance build beyond headers intake......
If this is has been asked oh well hopefully this will be quick in way of a simple answer or direction ware I can find it.
I'm having doubts with my bearing clearances. Long story short I have a reman crank that has been ground to .010/.010 or .25/.25mm under it came with bearings but there ACL alumaglides checked them out I dont trust them. I already had .25 undersized sealed power bearings, they are much better made.
I measured the the crank and rod journals with a metric mic and, with the bearings installed, used a bore guage to measure the difference of the rods and crank girdle.
So unless I need to recheck my crank and reset my bore guage I'm at .08mm clearance on the crank bearings and (I think, I'm going off memory at the moment) the rod bearings are at .05mm both of which are on the big end of what the the FM says. Technically the crank bearings are too big but the limit is .09 soooooo and it was like 4 in the morning when I was doing this so I'm might be a good idea to recheck.
What is y'all opinions? I was thinking just running it with thicker oil (before the rebuild I ran 10w40 syn blend, if I do just run it I'm gonna use rotella t5 syn blend 15w40. Honestly the only time I'd be worried is it startup.
The topic is now open for discussion.....
