Does a 1996 Chevrolet Camaro Z28 have a distributor?
Yes, it is located behind the balancer, all the plug wires lead to it. The distributor for all 92-97 Camaros, Firebirds, and Corvettes with the 5.7L LT1 motor is called an Optispark distributor, unlike most conventional ignition distributor designs, the optispark design uses an optical sensor and a trigger disc to send the ECM a high and low pulse signal. Located directly under the waterpump, the optispark dose require a fair amount of labor for removal. There are many options available for LT1 owners when it comes to replacing their malfunctioning Optisparks. The guys at www.all-ignition.com are the foremost experts on this particaluar ignition system and have the largest selection on Brand New Optispark distributors.

94 z28 camaro with a 5.7 liter 350 lt1 and it has the 460le auto trans recently purchased sat for a year in a garage this car has no power poor acceleration any ideas?
The problem could be your optispark distributor. They have a tendency to corrode inside and when this happens, it hinders the performance to the point that acceleration is greatly hampered. A bad optispark will also cause starting issues and engine misfires. Besides the optispark, check for a vacuum leak. Intake manifold leaks are very common on the LT1, as well as valve cover gasket leaks.

Did general motors ever put a Corvette lt1 engine into a camaro?
The 350 LT1 in the 1993-97 Z28s are considered by some as a "detuned" Corvette engine, but they never matched the Corvette in actual horsepower ratings (not officially, anyway)
