Big blocks are hard on 8 3/4's and the trans brake would make things worse. Your car is not real heavy but still over 3,000. You might be OK if it was a lot lighter but if your goal is to run super pro it is normally a full tree so foot braking is competitive in that class.




Super Pro around here is a full tree, and while I might be able to go some rounds at my local track, I won't be competitive at the big money bracket races without a t-brake and a delay box, not to mention I would like to try to run a few IHRA Hot Rod (aka NHRA Super Street 10.90 index) races in the future. Im shooting for eventually being able to double enter in both footbrake and super pro. It looks like a Dana is in order first though, thanks for the advice.
