We purchased a 400 small block for installation in our car. The engine is brand new and fully assembled. Yesterday my wife and I pulled all the main caps and rod caps to confirm bearing clearances and were shocked to see 030 stamped on the back of each bearing shell. I thought a crank turned any more than .010"/.010" was unsuitable for performance use. I think that the main journals on the 400 are larger than the other small block Chevies, but can I use this crank? Also, is .0018" too tight on the mains?
Thanks for your help. We are new to this bottom end stuff.

Sorry for the off topic, but do you own Cyberian Outpost Inc?
