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.
