How did these engines run with the lower compression and the solid cam...I always thought those cams required a certain amount of compression to perform properly??

I know they did the same thing with 71 LS-6 big block...interested to learn more.

Compression isn't a factor for the solid lifters. The main reason for them was the higher rpm. Hydraulics of the day would pump up at that rpm and hold the valve open/bend a push rod, or just collapse, if the oil didn't keep up.
