UPDATE:
I took it to that friend of mine and he test drove it and stuff and the resonator snapped off from the rest of the exhaust..so I have to get that rewelded..we think that was a lot of the squeaking noise--those too pieces rubbing together--but he also things something is wrong with the clutch. He says it's slipping. He seems to thing with that engine and all the stuff that's on it I should be able to get up to 80 mph in 3rd gear..and I'm bearing getting to 80 in any gear..Something isn't working right. Any ideas? Opinions?
