How much weight gain from adding a Dana and roll cage.

I saw a rat motored 67 ElCamino once that was claimed to be 4600 lbs at the starting line. I didn't believe it .....till I saw the driver get out.

He was 600 lbs, and the drivers side of the car,went up two or three inches when he got out, lol!

When I had my 70 Duster on super stock springs I sorted the suspension to get it to launch straight and wheelie straight. Played around a good bit with torsion bar settings sitting in the car.
I measured from the ground to a spot on the fender both ways, both sides, back and forth, till I found a happy spot.
there was about 1/2 to 5/8 inch difference with me out of the car :rolleyes:
