That is a very cool car and backstory.
Gramps was a member on here for a little while pre-restoration of the car.
Then after resto he gloated just a little too much and left in disgust.
It's a really great car and should cash out at around 500k.

How many RPMs would you have to turn to hit 140mph with 3.55 gears and F70x14" tires ?
Well over 6,000 I'm guessing.

Around 6500 RPM.


Long and smooth road could make it there? (at least once maybe :D)

I don’t think I would have wanted to have been a passenger in that car.

Impossible with an 068 cam and stock valve springs.
It wouldn't pull that RPM even in neutral or park.

Cool that he ordered it new and held on to it , and re-invested in a full frame off resto.
It's a great great car with a sweet color package.

Probably true. I was thinking more of my SD 455. (never had a 455 HO engine)

no chance this car could have 3.07 gears ? 140 mph would be more realistic with 3.07 gears and G70x14 tires.

With 3.07 gear & 26.75" tall tire/wheel combo behind a T-400, looking @ 5600 rpm or more considering convertor slippage. Well past peak torque & valves would be floating :(

Think it would have to be Auto AC , or Auto with Economy Axle , to get 3.07 axle.
Neither of those on the Invoice.
3.55 was standard in 71 Judge , Auto or Manual.
Top speed around 118-120mph

140mph speedo in a 71
Old campfire stories about burying speedometers in cars for extra clout.

068 cam with stock valve springs is like a built-in rev limiter.
