Are bearing clearances the same for alum connecting rods as with steel rods? I have a set of BME rods and Cleveite bearings that are tight by my standards (2.2" with .0015"-.0018" clearance, used bearings , less than 20 1/8 mile passes). The bearings and crank look good but I normally want to see around .0025" on that sized journal with steel rods. This is a large CI drag race only engine.

Thanks, Brian
