My suggestion on the 200 over the 700 is based on several write-ups in various cookie-cutter car mags. The later model 200s are prefered over the 700 because of the lighter rotating mass and gear spacing. Several of the Chevy mags have done a build up of these LATER YEAR trannies, and I think it is Chevy High-Performance in the last edition who did the most recent. They suggest replacing several of the internal bearings and the front pump, but they say in a light body (TF drivers know what I mean) the 200 will out perform the 700. Also they say it is half as expensive and more common. Not sure what years to look for, I have never run a GM tranny except for the old PGs and 400s.....Russ __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
