I changed everything up so I cant give you a good front vs non front.
I rear suspended my car when doing so, changed converters and tires, added 100lbs to the car. 60's doing this went from 1.04 to 1.10, 4.67-8@147 to 4.79-80@145. This would all be shocks and driveshaft doing this.
Its a 582 makes just under 1000hp, loose converter 6700 stall spragless, and weighs 1960 with me in it.
