T-bars vs Stored energy

for 6.80,s you should be low 1.42/3 sixtys. when my 75 duster was running those numbers with s/s rear springs i found the more i clamped the front and rear segments then tightened up the comp 3 way shocks to full tight , the faster i went . ended up with 3 clamps on the front and 2 clamps one the back. if you have poly front strut bushings they stiffen the front up tremendously, not good for a race car. front t-bars may be shot, it happens. mopar chassis book tells you to loosen thing up, unclamp springs and such. once you are running low 11,s high 10,s you need to control the violent launch as you have found out. keep videoing and use the time slip numbers to verify you are going the right way.
