ARE MY OIL CLEARANCES OKAY?
hello, i just had my engine built here in AZ by RPM engine development (aaron from full race told me to go here) and i had a concern on my main bearing clearances.... Larry the builer said the tightest he could get them were .0018-.002(the factory limit) i am worried that i might spin a bearing with them on the loose side.... he used clevite bearings, should i be worried? it is a b16 that i plan on running in the 400-450whp range what would you reccomend?
HERE ARE THE CRANK MAIN MEASUREMESNTS:
1- 2.1647
2- 2.1649
3- 2.1644
4- 2.1647
5- 2.1649
RODS:
1- 1.7713
2- 1.7713
3- 1.7713
4- 1.7712
DOES EVERYTHING LOOK OK? (I HOPE SO BECAUSE THIS MOTOR IS ALREADY ASSEMBLED AND BALANCED!)

Re: (irishflame27)
I like leaving my clearances a more on the tighter side and it has worked very well for me. It usually under .0015 but never less than .001. I still think that .002 is too much on the loose side. Many leave them around .0015-.0017 but if your builder knows what he is doing and has had success I'd just leave it.
