Center of Gravity and Roll Centers
One of the required bits of information necessary to properly design the suspension mounting points is the location of the vehicles Center of Gravity (CG). Unfortunately, I did not measure/calculate it properly before I disassembled the car, so I will need to reconstruct the CG based on information I've gathered on the web and some "rules of thumb". It won't be perfect, but I'm hoping it will reasonably close.
Below is a sketch of my estimated CG for a Stock Gen5 G-Body El Camino:
The vehicle weight and balance was gathered from several forum posts. The height of the CG was derived from the "rule of thumb" that the CG height is even with the center of the cam. I somewhat arbitrarily lowered the height by 0.5" to compensate for the difference in body structure between a sedan and pickup.
I then applied numbers for some of the series of modifications I plan on applying to the vehicle. A table of those alterations and their resulting impact is shown below along with my estimate of the net impact to the CG.
