@nsolimini take the pipe cap off, find a flashlight, and look inside. Do you see any damage?
You will see a wall a few inches in with a hole in it, is that wall secure?
Yours sounds like a transmission problem, lack of oil pressure or clutch problems. Seems to not be shifting out of 1st, that's usually the speed 1st tops out at. Or the cam lobes have wiped, but they usually pull a little more speed, their just lazy to get there and won't rev up properly.
