Chrisnben. Cal tracs will save you a cool 30 Lbs at most which is good, but after some track tuning/adjustments, it should high tail out of the hole and put you comfortably in the mid/high.40's.

I've improved my 60's with the right combo SS springs and some very good adjustable shocks. Cal-tracs are just not in my future plans. I'm too stuck up and hard liner for that factory look.LOL.

Chrysler SS springs weigh in the low 40 Lbs for each side, but are in the rear as semi-sprung weight.
I'm not sure what exact weight for the Cal's.

My friend who is currently building a beautiful stock looking street brawler using Dave Dudek Hemi power is also trying to trim fat off the front end and motor itself to basically try to bring the Elephant in the room down to Wedge weight.
