I have a stock 302 in an '87 notch that is/was all stock to start with and am running a Hellion street heat turbo kit and 10psi. The stock AOD gave up, put in a PA AODE with a trans brake, then the stock posi went out, now with a new True Trac and 275/60 drag radials i can pull the left front tire, but on stock old suspension i can't beat a 12.4 at 109. car weighs 2994.
Just got a big rear swaybar and Tokico D-spec shocks and struts with a coil over conversion and camber plates from Maximum Motorsports. Hoping to cut close to a second off the 1/4 mile time with suspension.
Right now the car leaves hard on the brake but once the frontend comes down it unloads the rear and i spin the tires past the 60ft. we'll see....
Trying to sort the new setup: FRPP 363SBF with an upgraded Hellion kit, 76mm, Trick Flow Box R, Holley HP EFI, Holley Water Meth, Holley Dominator fuel pump, Performance Automatic AODE w/brake, 3.27:1 Detroit, Maximum Motorsports frontend with coilovers, MM RLCA & sway bar.
