My day started at 4:20 am with a 4 hr round trip to pick up a Th400 switch pitch (thanks justbufords ). By 7pm I had the 455, switch pitch, headers, 3.73 posi rear, boxed in the lower trailing arms, front and rear springs/shocks all installed. What a difference it is from the 350 setup that was originally installed. A lot left to do but I feel like I made a lot of headway yesterday not to mention Im still dog tired. Before After
