Bought 2 of these, plus 2 14x25.4x6 main bearings, for my Go .25 and Go .28 race engines. They don't fit well in these engines - the front bearings sit too far out of the crankcase and the rears have too much movement on them allowing the crank to be pinched so it won't rotate when the flywheel is fitted. I gather the main bearings have now been re-designed but not much use to me with $100 of useless bearings. I understand Boca's fit perfectly so guess I'll be trying those instead.
