engine swap

[Werewolf]

These trucks came with the old granny-low first four speed transmissions. I actually don't remember any of the details about them. Depending on your rear gears, first may as well be useless. I never used first on a 4:11 geared K20 when I was younger; there was just no point.

Other than that, you're looking at a Muncie or Saginaw four speed out of a car. The trucks never came with 'em. Right now, those are only going to get harder to find, and cost a good amount. I don't know what setup you've already got, but if you have a stock four speed now, and you don't want to go through a ton of work, stick with what you have.

If you want to be different, pick up a later model 5 speed out of something like a 4.3 V6 powered S-10 if your HP application is lower, or maybe a more beefy 5 or 6 speed out of a 90-02 Camaro or something. Then you could run some nice, tall gears and still have an overdrive.
