Check for an exhaust leak, check the exhuast manifold bolts. Very common for them to break on the early LT1. moost common is the one under the alternator and the driver's side rear.

Also check the anti-backfire valves on the exhaust manifolds, if they go bad they sound like an exhaust leak. Pull the rubber hoes off the exhaust manifolds and start the car, nothing should be coming out of them!
