GenIII Hemi w/5-Speed Supra Trans?
A lot of it really depends on what you plan to do with the car. I had every intention of mine being a street legal drag car until I started driving it more. I really didn't feel like hacking up the body for tubs and a cage, so it's become more of fun cruising car with good power. Because of that I was really drawn to an overdrive trans for highway cruising to work and back. If you're just running around town or racing the overdrive likely won't get used much and the extra speed(s) won't be missed. I had an 833 in mine for a few years before I got my T56 setup. Worked just fine and really the car didn't mind cruising at 3000-3500 on the highway (3.55 gears), but I didn't enjoy it as much.
