It has a mopar electronic distributor with vacuum advance, stock build engine, electric fuel pump. The timing is set at 14 BTC. Everything runs fine but the engine stalls out at around 60 mph. Any ideas what could be causing this?

More details, was the eng OK b 4 (if so what was changed) or if another eng was it OK w this elec pump setup? Is that cruise or WOT at 60 MPH. What carb? What they said, check float level/filter(s) (inline and carb internal) and might put a T at the carb inlet & run a line to a vacuum gauge taped to your windshield & see if have several PSI at the offending sp (60MPH), Most of the hand held type vac gauges have a PSI side for pumps EDIT read your last post, might put a can of gas in the trunk & run a section of neoprene line down to the line at the sending unit to bypass the tank & take her back out & you'll know immediately if the sock is partly plugged.

Also, the flow out the tank when we had the pump inlet hose disconnected was a little intermittent so we blew back up the line into the tank. After this, it looked like we had better flow. Maybe the sock filter is a bit dirty and that caused the pump to go bad. I guess the next thing on the list of things to do is change the sock filter in the tank to keep this from happening again.

You might cut the filter open and look at it, if it is excessively dirty then I would clean the tank and replace the sock. I just went through this with my car yesterday and the sock was disintegrated and allowing garbage to be sucked up the line. My car would seem to run out of energy under hard acceleration. You would be amazed at the amount of crud that's in there.

I have a new 3/8 sending unit if ya need one. Also no need for an electric pump on that car. Just go to NAPA and get the pump they have listed for a 440-6 car and roll.
