hey, sounds like you have a tire out of balance, so go have those checked first.

Could also be a busted belt in the tire, I see it every so often. You didn't state how it originated, all of a sudden or after some work that may have triggered it.

Third gen camaros are notorious for the death woble due to imbalanced drive shafts. Check as well.

I had a 69 Road Runer that did the same thing, I had bought a bogus set of 60 series tires from a tire shop and the car ran fine until I hit 70 mph. Then the rear would shake until I powered through it at about 75. I went back to the shop and they just couldn't get them to balance. A new set of tires quickly fixed the problem. Boy was I stupid to sell that car (well hind sight is 20 20)

Regards
Mark

My nova starts to wobble at about 65 and i havnt had anyone tell me its anything but a tire being out of balance. Take it to a tire shop and have them check it.
