The frame is fine, I have had it up on lifts. It has a whole new engine, not just rebuilt. Before it ran great besides it would die out when you stop really fast. I am not going to lie, what ever simple fix you think it would be, its not. I have replaced part after part. The engine needs to be pulled and rebuilt because something is not right. My best guess is that the dude put way to big of a cam in there.
