We felt so good about getting the 440 running the 68 New Yorker, we decided to try and start up a 68 Newport that has sat equally as long. Unfortunately, success eluded us but I'm not sure why. So this Newport I bought in '91 as parts donor for my 68 New Yorker. It ran when I bought it and I drove it to where it has sat since then. We checked the oil and it was fine. Hooked a battery to it and it cranks. However, instead of the typical chug chug cranking, it just spins "evenly", almost as if the spark plugs were removed, except slower. All I can think is that the valves aren't opening/closing. Could it be that it still had the original nylon coated timing chain gear and that just gave out as soon as we turned it over? If that's the case, would the valves open/close, but just out of time with the crank? Or would there be no valvetrain action at all?
