What type are you using what kind of 60 ft 0n a 10.5 inch tire looking for 3500 cars and heavyer bolt ons control arms:TU:
1970 Olds Cutlass, Olds 455, Th400 w/brake, 10.5" tire. With stock arms, No-Hop bars, 1 air bag, and factory sway bar I ran consistent 1.55-1.57. One time I went 1.52 in great air. I switched to Dick Miller uppers and lowers and it ran about the same numbers, but it left more even, and I didn't need the air bag or the sway bar. The Buick I have now has Dick Miller uppers with Global West lowers. I haven't made a hard pass, yet, because the car isn't done. We'll see. Have fun.
I bought this rear setup from Wolfe Racecraft No times as I'm still putting the suspension and motor together. They use this stuf on late model mustangs into the mid 8's in the 1/4
