64 impala I have owned for 20 years. I did the ls swap and 4L70 about three years ago. The air suspension 15 years ago. Car has global west upper and lower control arms, 2 inch spindles, big disk brakes, cpp 500 steering box and hellwig sway bar in front. Bc fab lower link bars, bc fab y bone upper, 2 inch mini notch, telescopic drive shaft, billet carrier bearing, bell tech shocks, and air ride rear sway bar. I have had it chassis dynoed at 430 hp and I average 21 mpg. Inner fenders and rear filler neck compartment have been changed for tire clearance and front frame rails have been notched for tie rod clearance so it can be driven extremely low
