how do u figure that?  
i came from B series… and the friends with all motor set ups, and NONE need the be rebuilt that early ever and they always being pushed!! Im not hating on your statement, i just disagree! All motor is more reliable by a bigger percentage!!.. if any of your friends are rebuilding every 10k or sooner tell them to find a new builder!!
