I'm not running a BB, but when my stroker was built, my rings only lasted a few minutes. I was sucking a quart of oil every hundred miles or so. It was theorized that my Demon carb washed the oil off the rings due to jetting and insufficient advance. After she failed a leak down test, my pistons were removed and re-ringed (the original rings were completely worn down). I took my car to a local dyno and they ran a bunch of pulls, rejetted the carb back to where it was when originally installed and cranked in a bunch of advance to get the A/F ratio right. That was 12K miles ago and all is well. A few other folks down this way had similar experiences.
