318, 340, or 360?

Very nice looking car - you do realize that once you start changing things - - the proverbial "can of worms" opens and it can get out of hand VERY quickly. With that said, it really depends on your goals for the car - reliable daily driver (318), street brawler (340), weekend street/strip thumper (360) or all out race car (built 360)? (just staying with the engine options you have specified)-- how deep are your pockets?? are you ok with the car being "out of commission" for just a weekend or two, a month or two, or for 1/2 a year while it is being transformed?
