Totally agree-A stable, happy and RELIABLE valvetrain @ 7000+ is not all that common or easy. Most 340's I've tested are pretty much done @ 5900-6000--Will they rev to 7000 rpm if asked to--Yes most of the time. Will they actually keep you pinned in the seat all the way to 7000-7500? Not in my experience they won't. Thanks for the comments. J.Rob
