Dear happ:

I know that method has been around for a long time, but why it shows up on older vehicles is a technical question.

Anyway, that gas line is too close to the manifold.

If I had a case like that I would carefully heat the gas line with a torch to see if the car stalls, then do the same with the clothes pins attached. Maybe those manifolds are eroding and transferring too much heat into the motor compartment. Given Packard's propensity for heat shield they apparently were able to produce such problems at the proving grounds.
