So my buddy that is desperate for an overdrive, is suffering from a self-inflicted wound. His Firebird 400 came with a 4 speed, but it needed work and he was a dumb teenager. A shop talked him into swapping to a Turbo 350 that was all built up. The clutch pedal is still tie-wrapped to the floorboard. I forget what rear gears he had but he eventually swapped to 3:73 gears and low profile tires. I warned him, he did not listen, and now he is highway traveling in the slow lane with his flashers on because he can't keep up with today's overdrive speedsters. He wants to have a manual trans again, but none of the usual options comes in overdrive. Of course a relatively inexpensive rear gear change would solve everything. But he is one of those that doesn't know how to back up and regroup. He just keeps throwing money at a problem hoping to fix it. Thus, the desire for an overdrive manual trans.
