I had a buddy who swore his dad did the same with their Buick station wagon on long trips. I don't remember if he switched to straight Kero (JP-5/Jet-A) or a 50-50% mix like JP-4.
Back in the 1980's, I helped friends in Kenya drop a 283 Chevy V-8 into a Land Cruiser Pickup (the L/C Straight-6 is a copy of the old Chevy 6, so the 283 bolted right up!) When I asked about it years later, they said they'd sold it to a guy who was running it on kerosene!
Fact!It was a nock off. they cloned it and tapped it metric. Same critter. It was the same as the L 6 235 chevy, bell housing and all, which was the same as the 283 small block. We did a few of those swaps here in the states back in the day. :)
