66 Dart GT HT Whatsitgonnabe?
I could try tagging
@krazykuda and see if he shows up.
Did you ring???
I would do a compression test on it. do it dry, then wet with a couple squirts of oil in each cylinder and see if the numbers get any better. Then go from there...
Did you have a pressure gauge on it? What kind of oil pressure did it have when you had it running?
