If I had to do it all over again and went mild: Dogbone/polymount, trans cooler, shift kit, elect. cutout. If I wasn't happy with that I would of gotten a tuner that could adjust timing and put a small shot on it and be done. I do not rec Magnaflo, way too much drone!
Believe it or not before I went mod crazy, one of the biggest seat of the pants performance mod was the shift kit and dogbone/polymount. The car felt so so different after that mod.
