I understand there 8.2 8.5 and 8.8 inch gm 10 bolts, each one progressively being better suited for higher horsepower apps. true?
which of those is most likely fitted on a 1968 El Camino with a 307 and 2 speed glide?
or better yet, is there an easy way to find out myself?
if it is one of the less desireable models, do i have any options for beefing it up to withstand around 400 hp? what would i put on my parts list if someone handed me seven or eight hundred dollars for the rear end (which is close to my actual budget)
