If you don't want to spend much you better stop right now. To do the job right you'll basically need to change out the whole drivetrain & more. New bellhousing / clutch, trans with slip yoke, custom driveshaft, bigger rear end, bigger brakes, bigger wheels/ tires, upgraded suspension with swaybar, and the list goes on. The Dougs headers work well with minimal fuss but you will need to use the special Robb starter with the 10.5" bell, that setup alone will be north of $1k.
