The reason they didnt have one for the S.B.C or any other piston motor was because they couldnt hold oil pressure because they were a two piece design. They have them now in high end sports cars like the {bugati} i geuss is how its said? I think this needle bearing design would increase response and horsepower do to less friction. Its like hydraulic cam vs roller cam. If there was a way to machine these bearings for the 13b, would you have to mill down the e-shaft or bore the rotors and stationary gears?
