Finally chased down a vacuum leak and got everything running fine and niw have a bad vibration at the rear under high load situations in all gears. Shifter doesnt shake so i dont believe its the tranny. I have a 9" with maybe 1500 miles on it and bo issues before. And i didnt have a problem before i pulled my intake manifold to fix the leak. Damn car always has a problem. Im going to get under there to see if i broke anything but figured id get the ball running on ideas. I have a spare tranny mount so i might as well change that and ill tighten the u-bolts to the rear to make sure thats not the issue. Any other ideas?

After driving it around a bit more i think it might by my clutch nit holdibg the power. Ive had clutches fail on me in the past and i would put it in a high gear and punch it and watch the rpms go up. This feels more like clutch chatter. Is that a symptom of my ls7 clutch not holding the power? Made 550rwhp
