I am having a bit of a dilemma deciding which one to get. Should I get the 331 stroker kit or the 347? This motor is going to be in my daily driver. I want this car to have BALLS and I will also be taking it to the track as much as possible (mostly only weekends that I have extra money). I also want it to be streetable. Is one more reliable than the other? How much of a power difference can I expect from the 2 (if any).
