1G Oil clearance

[Anthony Boni]

So I know stock oil clearance for the mains is .0008-.0020 with the limit being .004”. I have a NT block with BS deletes and I was wondering what I should shoot for to keep idle and WOT oil pressures under control. I also plan on doing the head oil port mod as well as porting out my OFH. I won’t have oil squirters so should I aim for a .003” or try and keep it within that stock limit? Thanks!

Depends on your power goals. Stock power Stock limits. If Your upper the power you could use hx bearings for a slight increase in oil clearances for more power and heavier oils. Typically .001" for every 1" of journal size, should keep you in the green.

keep it within that stock limit? Thanks!

Not yet. I will update this thread when I figure it out. Probably going to use ACL HX bearings for a tiny bit of extra clearance, though.
