Mixing bearings for clearance

Ok, I can say have never personally done this (yeah I havent)

It has always and I mean always sounded just "wrong" but I also havent built a stock eliminator motor from "scratch" so....instead of things I havent done, onto things I may have to do. And I actually cant be playing with the crank a whole lot on this motor to get the clearances Id like....I a)dont have time b)bought the last crank in stock from Ma Mopar in the country

I know were talking hundredths of thousanths, any issues on this ? I dont see any other than my "im used to roller bearings" aversion.

Also, and I know this is a "preference" but since its my first Stock elim motor. On a say rod, where am I looking to be for a motor that is going to be beat to death with minimal breakin of course. I was thinking .0026-0028 ? Is this sounding inline with what others are doing on say a SBC "stocker" ? Same journal size and bearings....

Im using coatings on the crank so Ive got to take that into account, but well.....Gotta do the motor asap......

Cheers

Chris
