I think you are fine with that. I would run it.

I talked with the machine shop I use. They said full groove main bearings are not a requirement when using straight shot oiling.

We use 1/2 and 3/4 groove main bearings in Crower and Moldex billet cranks which have straight shot oiling. I like the extra support for the crankshaft in the cap area.

Try some Sealed Power main bearings. They normally measure quite a bit small than the Clevite's, thickness wise. They are 3/4 groove too. They may get you the extra clearance you're looking for.

Thanks everyone for the responses. I have one more bearing set on the way and I’ll decide after that what to do. Be watching for bearings on the Parts for sale page ��.

Have the block main line honed to max spec. try diff brands of bearings, they all seem different

I could get a set of STD and close that up to about .0025" to .003". Suggestions?

Your clearance of .003 to .0035 is ideal you can't go wrong with those clearances.
