ok, this is killing me, it really feels like a broken motor mount but not sure, when hammering it car bucks to the right, when i get off the throttle, has a thumping feeling in front end, has vibrations at and off idle and at high speeds, any help would be of great help right now. afraid to hammer the lt1!!!!!!!

 

ok figured it out, murdered a tranny mount. replaced with a es poly mount, much better now.
