I have a 70 nova with a TH350. I am really thinking about puttin a shift kit because my 2nd to 3rd shift is quite sluggish. The B&M Shift Improver Kit seems to be the obvious choice but I also intend to take my car to the drags every other weekend or so. This is my daily driver but i would really love snappier shifts for the weekends! The Trankspak comes in Stage 1 and Stage 2. It claims to be for performance street use. Would the Transpak be to harsh for daily weekday driving? Which kit do you think I should go with??? Thanks
