I have the 3.54 and the .64OD gear ont the TKO600. The 5th gear is only used for pleasant cruising, not for racing. BUT, I spec'd my engine so that the first four gears allow me to hit 140 (solid cam, so I can rev a little higher). I think what you're looking for is more torque, not having to shift quicker. Assuming your dyno-tune doesn't get you a whole lot more power, the heads and cam from one of the guys on this forum is, roughly, a grand or so. Maybe upgrade the rockers as well. It's a one day job for your mechanic to bolt the heads on and stick a cam in ASSUMING you can do that without pulling the engine. We're not talking a huge money investment here. I wouldn't mess with your rear end ratio.
