Make sure your tune is spot on by using the techniques described above. For this very reason, Mopar engineers went as far on some models as to have an electric solenoid that shut the throttle even further when the ignition was turned off.
In the meanwhile, have him shut it off in drive before putting it in park or let the clutch out gently just as he shuts it off.

1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

Carb is too far open at idle.
 just slow your idle down slightly & if you have to bump your initial up a bit
always been the problem for me too. Idle set too high. If my distributor wasnt set up right to allow me the right advance as idle, i would have had to speed up the idle to get it to run in gear.
An easy workaround for that problem is shutting the car off when youre still in drive.
the correct fix is to mod the distributor and then turn the idle down

Depends on what's causing it. I've forgotten the details, but there are certain lashups concerning alternator conversions that can cause power feedback--is your wiring original?
Also could be a hot spot in a head or even plugs that are too hot, or just running too hot (check your temp gauge) and / or too lean
Yep, it's the reason Chrysler went to "idle solenoids" Back in the day you used to hear a car "dieseling" all the time in parking lots.

my big block does it when it gets hot. it's super annoying. turn the key off and it shuts off, fires back up for 1, maybe 1.5 seconds, then dies again.
what's odd is that the darn thing used to run at 180 all day long, and on cooler days on the highway, wouldn't get over 150...I drove it around in the winter and had to put cardboard over the radiator to get it to maintain temps.
then I got a leak in my heater core and it started running at 195-200.
I've since gone "heater delete" and removed the hoses, so I hope it goes back to running at 180
