Hate to hi jack this thread, but that's impressive being a big block car , and keeping the 8/14 together. I have an 8/34 A body rear with 3 different center sections which to choose from. My car currently has a 8/14 in it and would like to stay with that, but it's an open 3.21. Been thinking or some track time next year with this car. Stock 360 and street tires, and possibly dot type slicks, just not sure yet of my options. Sounds like the 8/14 can take some punishment. I just wonder if running an open diff would make much difference than a sure grip with decent to good track prep and street tires with a stock engine.
