My car has American Torque Thrust Mags and a Thunderbolt hood. I converted it to a 4 speed Toploader with 1 3/8 input shaft. I have a 3:50 traclock posi with 31 spline axles. In 2012 I had the 428 completely rebuilt using forged pistons and forged connecting rods with Edelbrock aluminum heads and 2-4 barrel Holley 600 cfm carburetors.
