...hmm, its prob a 350, or a 302... One thing to figure out first is, how you want the car to perform, do you want a daily driver with great handeling inthe corners, and a snappy responce? Or do you want a drag car, that shoots down the road in a straight line, and doesnt perform as well in the corners? Whatever you decide, Weight control and HP are both and in hand, you can never have enuff weight control, and you can have too much HP.
