Hi,
Although the wrong era, I had a '62 Chevy 'Suburban/Carryall' (with dual ambulance doors in the rear and two doors up front) that I had rather fixed up .... 3/4 ton variable rate springs, anti-sway bars front and rear.
Then there was the engine ... I had found an old Offenhouser 4 bbl manifold in a junkyard, and put a Holley 450 on it... and I met a man who built race distibutors ... had him take a '69 HEI ignition system and throw away anything that had to do with smog ... when he got done it was a fully centrifugal distributor.
The thing had instantaneous torque ... in the lowest gear of the Chevy 4 speed (actually more like a 3 speed with a hellacious granny gear) would pull stumps out and never get over 1000 RPM. And it was so low that I could literally walk along side the car and steer it at 800 Rpm ....
The gas finally got to me ... I was commuting 60 Miles one way to the USAF Reserves at Travis AFB twice a month ... and I sold it to a friend who still has it (he uses it just for hauling and camping.
On the one hand, I wish I still had it ... but I could never afford to even fill the 20+ gallon tank up ....
