Burn out issues

Read what OldManMopar posted about 6 times. I would also think that "weak spring flex" can cause this, think about how springs work. They arch and change length if they are not strong enough under extreme power. When they twist under power they change length. The old 70RR 440-6 had the "trak pak" It had I think 2 extra "half leaves" under the front of the right rear spring to stiffen up that part of the spring.
