Nice truck! Just my opinion, but are you sure you want to go with the O/D? Guess I'm a bit "old school", but your already setup with a TH400 (probably one of the strongest trans. GM ever made) and a 3:08 diff which is close to a perfect match. Running the 400 you will not have to install any electronics, TV cable & adjustments etc. I have had too many BAD experiences in the past with high performance engines and overdrives. (put 3 700R4's in my 82)
I'm not familiar with the 200.... maybe it's a better trans.... Guess it also depends on where you do most of your driving..... around town, the 400/3:08 would be perfect, on the highway the overdrive will shine....
