I've been planning my ls swap for my car but I'm having second thougbts because of costs, plus I need to get the car drivable before summer. So I had the idea of swapping the heads and intake from a vortec or tbi engine onto my current short block. It runs fine but I really want efi for the reliability and mpg's. Will I gain any significant fuel economy from this? I'm hoping for at around 18mpg in the city. Is that number acheivable. It will be backed my a muncie 4speed and I haven't chosen the rear gears or tire size yet so I can pick whatever will be best.
