some C-3ers like the 200r for the overdrive 4th gear. keeps the rpms down. dissers have complained of problems and poor reliability with the 200r. you know the drill. opinions are like a**holes. everybody has one.

i believe the 200r can be swapped out virtually directly with the 350 with a bare minimum of modifications. i don't think that's true with the 700. i believe that requires quite a bit of mods (and know how). others may have more to say about this.

I have not put in a lock up yet so that should give me another 200 to 300 RPM drop. It is GREAT!! I have not checked milage yet been having too much fun with the lower first gear taking off faster! I used a 400 Turbo cross member but after I looked at the cross member I had with my 350 tranny I think the 350 one will work just fine. Just unbolt the extra plate and bolt through the holes. The 700 R is longer and you will have to change the drive shaft. With the 200R you don't have to change the drive shaft. Just buy a BEEFED up 200 R and you won't have any trouble. The shop that built mine said he has them holding up to 10 second drag cars. Just be sure you set your detent cable right.

Howell, Street and Performance, Painless, etc sell a lockup kit. If you have done a fuel injection swap, you can let the computer lock it. If you had a TH350 with lockup you can still use that.

I've done a lot of mod. "stuff" to my 78 but the BowTies 2004R was the very best thing I have done! I did add a rocker switch to force it out of overdrive for those times when I'm in traffic and need to be able to accelerate to keep up with traffic flow. I don't drag race mine so I don't think I will ever have a problem with the 2004R.
