when i called dart the guy checked with their engine builders on the main clearances. he did admit they were winding them pretty high @ 1500hp so i'll take it with a grain of salt. i guess it depends on wt. of
oil using, but i told the guy 10w30 and he said that was a good
oil and was pretty sure on the .003 mains. i'll prob end up with around .0025 to .003, but he said not to get into the 2's and initially said .003-.0035 and .003 on the rod pins. i would think idle pressure would be pretty light with those clearances, although idle doesn't take a lot anyway. also, this is with priority main oiling and you prob couldn't run those clearances if it had to go through the valve train at the same time.
olddog, i'm gonna need some more fingers after about the 5th cleaning if you have any extra.
