hey guys, i have a 200R4 in fleetwood caddy with a rebuilt 307 engine. I wanted to knowhow can i update my 200R4 into a more stronger transmission that will hold up against a more bigger engine. Like when i take it to get rebuilted, what should i demand i want done to it to perform better than original look and hopefully a 700R4 if possible.............

 

The input shaft of those 200r4's will definitely not stand up to any high torque. What kind of motor are you putting this behind? On of the best site's for info on this is http://www.turbobuick.com/forums/. There should be lots of info there or guys that can help.

 

Go to Bowtie overdrives for all the parts you need to do it. They have a lot of good info on their web sight
