body kit you will lose value on number 3. That Z is for someone else going in the oposite direction. Who cares what the paint looks like as long as the body is solid. You will have to repaint after the kit is installed. As far as the motor; the price diff. from #1 to #2 would add thousands to your engine mods. Use this forum to try and do as much of the work as you can and use a shop or a buddy to finish the rest. If you think the mods on #2 is greater than the price differance on #1 and it will start you in the right dirrection for your goals then go that rought.
