Gf is right - you need to get that bad boy running again!

The jet engine car idea reminds me of a couple of cars at the Oswego dragstrip back in the 60's. One was a jet-powered Volswagen called "The Lightning Bug". The other was a jet-powered Camaro, but I forgot the name. I think the "Bug" turned in a speed of 204 mph in the 1/4 mile, and the Camaro turned in a 209 mph! So, your Dad's idea could work with the right engine.
I KNEW the truck was for a preparedness/bug-out vehicle!
