Tranny education

[piecesparts]

I took my 350C out of the 84 and installed a 700 in it's place, the length difference was ot that much different, but since I had lowered the truck, I did have to change the driveline. There are two differnt lengths of 350 tranny tubes and if you have the longer one, the changeover is not that bad. The mounting bracket will have to be moved for the rear tranny mount and the changeover for the cable is needed, but that is not hard. My tranny is mounted behind a 400 plus horsepower stroker motor and it is handling it well. However, I went ahead and replaced the planetary and clutches in it to ensure the longevity. I would recommend a tranny upgrade BEFORE you insatall it to be ready for the big block. I changed my rear end gearing from a 3.42 to a 3.73 gear and I get around 2500 RPM at 70 MPH, that puts me right in my power curve for the engine. It is one of the best things I ever did for the truck.
