The extra 3 or so bhp is a big percentage increase. Hill climbing in 3rd especially is much improved. But Austins did delay hc until the 3 bearing crank for reasons. The 2 brg engines are distinctly more harsh. And raised cr is severe on the original cranks. Many loads increases in proportion to cr and if you read any elementary text on metal fatigue the effect of a 30% or so increase is interesting!
