I plastigaged my main bearings and I'm getting somewhere between 0.0015 and 0.002. My manual only tells me that it shouldn't be more than 0.0035. Is the clearance going to be too tight? Also, what would be an ideal clearance for the rod and main bearings?

 

On a bone stock 350, I believe that is within spec but on the tight side. How do the bearings look?

 

They're new, they came with the crankshaft in a kit.

 

Also, the engine is not bone stock, it has forged flat top pistons.
