Hey folks! I've got...
I started by measuring all of the the main journals on the crank and I got a range from 2.358” - 2.360” (I used a digital caliper and I'm pretty sure I did this correctly). Then I “dry-fit” Silverline STD/STD main bearings into the case (sans crank), torqued everything down, and got 0.003” in radial play (I used a cylinder bore dial gauge for the first time, and I think I did it correctly). The spec-sheet says radial play should be between 0.06” - 0.10” (0.03” - 0.09” for #2); and I have 0.003." I'm a MINIMUM of 0.057" off, is that normal? What's my next step?

Life gets in the way...
Just before we moved to Granbury, I was DEEP into a E36 BMW M3 coupe restoration. I had to put the car on hold when we up-ended our world with the move. This was 10 years ago. Life happened! Career with TELCOM ended due to poor management practices. That got closer to killing me than anything else I've ever encountered. Dad got cancer. I had to open the shop. "Doesn't work well FOR others" applies to me, especially after TELCO. I have an extremely nice 98 M3 that's just waiting for me to get back at it. Important lesson with M3: Don't purchase new tires UNTIL you have the car through initial functional testing. Run and Drive BEFORE tires. I have a NEW set of DWS Contis on restored wheels on shelves now. Dates are 11 years old... I understand your dilemma SuperHawk! You still need to finish it, however. Enquiring minds want to know...
