Fought with clearances most of the day with our LS1. I've been trying to use plastigage, but my clearances all seem to come up too tight. My mains were coming up with .oo1-.0015", and the same on the rods. Stock 2001 block that only had 40,000 on it. stock polished crank, standard King bearings on rods and crank (CR 807HPN- MB5013XP). Eagle h-beam rods. I'm a little lost as to how any of this could be too tight. Questioning the accuracy of Plastgage.

Plastigage is only slightly better than guessing and shouldn't be used for much more than verification.

If you want accuracy, a mic / dial bore gauge with 0.0001" resolution is the way to go.

^^^^yes listen to him if you want your motor to last more than a few hundred or maybe thousand miles

I'm going to order a dial bore guage. On a side note, has anyone ever seen an Eagle rod that the big end was undersized on???
