230 miles tow it or drive it ?

I would drive it.

I have a copy of CAR's magazine 71, they road tested the 340 Demon with 3.91 gears, they said the car seems to be built for speeds 70 mph and faster

There was no crying about the 3.91 gears, back then 4.88 gears and 80 mph was no can do

Many trucks have speed limiters set at 65 mph, you could just find some nice looking truck and pull in front of it and ride together at 65 if you want to keep the revs down. Yeah some would hangout in back of the truck but then you can't see too far ahead
