Re: Rough Idle and Jerking at Constant Speeds
First thing I'd check is the fuel delivery. If it is a Holley, pull the needle valve assemblies out one at a time and flush them both directions with brake cleaner. Use a filter in-line between the pump and carb. Spark plug wires would be next - if they have much age - replace them.
OLDED - It's STOCK if it's made by GM and it fits!
