I am dropping off my motor to be built this week and i am trying to figure out what kind of clearances for the main and rods I should go with. Should we do stock? It will be more of a street car with occasional track use. See my sig for info on the motor. any help is appreciated..

 

I've always shot for .002-.0025 on the rods and mains and run straight 30wt oil with a standard volume pump. My bearings always look great. I am not a professional engine builder however I was told to run these clearances by one.

 

I have no say for the bearings, I wanted to say props on the engine. Looks like all quality components.

 

local man? perkasie? second should beable to tell you what clearances to go with they have built plenty of motors

 

Let the builder decide on the bearing's, if your doing it right you have to start mocking things up first before making that decision.
