I assume you have the LT1 in this. It sounds like the distributor is cross firing and causing a misfire and backfiring. You could have a leaking water pump leaking coolant onto the distributor too since it's under the water pump. It's probably due for plugs, wires and a distributor with cap. It's pretty expensive to tune this one up.
