Overdrive options

Thanks, Do you know what's involved in making the swap?

An adapter kit of course. A few companies make them. Wilcap would probably be my first choice. Don;t let anyone tell you the 200 is weak, blah blah. GM put that transmission behind the 3.8L Turbo Buicks of the 1980. You know, the cars you could add a chip and slick to and run 10s? Yeah. Those. The ratios are really close, too. Yes, you have to build them to performance specs, but the cost is still cheaper than a comparable Chrysler OD, plus you don't have to hack the floor or cross member up. A custom drive shaft is required of course. Big deal, right?
