My son will beat on his car and it will see track time. It will at one point I think have a GEN3 Hemi that's boosted. He was sold on using and building another 8 3/4. This thread has been very enlightening for him. I think he's already talked to Dr. Diff. . He was going to put rear disc brakes on it but now he's waiting to do the front and rears at the same time. Keep it going it's all great info. mtt
