    What are all the main bearing sizes used over the years in blown V8's? Didn't Arias use Ford and Cadillac? What were those diameters?

    A BBC is 2.750", what is a stock Chrysler Hemi?

    What does MBR and Keith Black use?

    I see in the classifieds that there is a MBR crank for sale with 3" Olds mains. Apparently Olds had 3" mains, is this common in a Minor Bros engine?

    That used to be the case. They've since been remanufactured...
