How big a deal and how much money would it be to swap in a Muncie 4 speed or other manual trans? The car currently has the automatic shifter on the floor. What kind of performance gain would I see in the 1/4 mile? I would be starting from scratch.
Manual trans is "kick in the pants" fun for cruzing around, but you will find the automatic the trans of choice for drag racing..
The switch will require adding the clutch pedal as well as swapping flex plate/fly wheel and many necessary items (bell housing, clutch etc.) Drive shaft length, wiring for backup lights and speedo cable are some of the other items that come to mind. I don't think it would be that hard of a job, just work out the details before starting... Find a stick car and start comparing and take notes. Good luck,
