318 missing and stalling once warmed up and at cruise

Jason,
Do you have a genuine LHD Dart or is it a VF/VG Valiant coupe?
Hey Bewy... I just saw you are local! Here is the Ad to the Dart I bought -
[SOLD] - 1968 Dodge Dart GT
Perhaps you could send me your number and I could reach out direct, if you're interested as opposed to messaging etc :) (if appropriate) ...I'm gonna go out now and fire her up to test the oil on t/shaft you suggested...
