Is this a Carb or EFI system also the type of Ignition system
Try this remove the PCV valve-the rpm should drop atleast 50rpm when plugged and raises when unplugged. No changes inspect valve and vacuum passages.
Also perform a fuel pressure test.
Double check all connections at plug wires at spark plug and distributor to include the coil wire from coil to dist. Cap.
Does it have a mechanical vacuum advance?
Spark plugs is it the correct type and heat range.
HTH Good Luck!
