Need some direction with my Mom's 64 Dart

wow, thanks for all the feedback. Yeah, it seemed pretty high but I also think he's probably quoting for Murphy. As they typically work on more modern cars.

I will try the oil first and see what happens. As for keeping the car, it's not costing me anything. Just sitting in the garage. I think sourcing a new engine would be the best rout to take (if this one is a no go).

I don't mind doing some of the work myself it's just budgeting time and the expense of getting all the equipment necessary to get the job done.
