GM never made a car besides the Camaro and Vette that had a 700, so any 80's - early 90's Caprice, Monte Carlo, Malibu, Olds Delta 88 and Cutlass, Pontiac Parisienne, Grand Prix and Bonneville or Buick Regal/GN and LaSabre with an OD tranny will all have the 200. They are ysually very easy to find.

My 700r4 came out of a 89 Firebird.

Remember guys...Art Carr doesn't start with your average 200...he uses parts from the buick GN version...rare and $$$$. Your run of the mill 200 is much weaker than the average 700. I went through two of 'em [both 'built' by a reputable shop] behind mild crate motor.

No, he doesn't. There isn't that much difference between the 2. He uses a heat treated stator support and heat treated and annealed intermediate drum assembly. Those are the biggest weak points, but even then they will support 450 - 500 HP without them, if properly built. Those parts are the same in a regular 200 and GN transmission. The clutches, the servo, and governor are the main difference between a regular 200 and GN 200. I've broke 700's behind 305's so in stock form, both are subject to failure. Either will have trouble living behind the torque that Popntiac is making in stock form.

Our local transmission guru says about the same thing I do. He will actually recommend one though where I won't.

He tells me there's more than just a bit of difference in the two 200's, but I am not here to argue with you. If you think they are better that's cool. In our area, I can't find one person who agrees.

Personally I wouldn't have either one. Both of my trucks will be getting a 4L80E....undoubtedly stronger than either transmission in this thread and a much better platform to build from.

I'm not not to argue either, I have just had great experience with them in quick strip/street cars and I've seen a lots of 10, 11, 12 second cars running 200's. They have really become popular here over the last several years. I have another one built and ready to go for my red '69, but its only going to be daily driver. I'm only going to be running a Vortec headed .030 350 with the Ram Jet 350 roller cam, so its going to be a mild set-up.

There's no doubt that the 4L80E is better than both. The cost is only negative with them.
