Properly installed the TF-SC shift kit in your application is an excellant choice. My Challenger (1974-360 STOCK) has one put in it. On WOT it'll bark the tires like I had a larger more agressive kit in it, yet under normal throttle, it shifts just slightly firmer than a stock 727. Because I worked in the industry, I know a lot of good builders. As my car had sat for almost 30 years with less than 3000 miles on it during that time period, the transmission had a lot of leaks so I had it re-sealed and gone through. The builder knew what I was going to do with the car, so he suggested just the small kit vs the TF-2. A good choice.
