Hey guys hows it going? This is the first time that I am posting a thread on Colorado K5.I live in San Jose CA... And I bought a 1986 K5 Blazer, and soon found out that i need a whole new drive train. Everything is stock right now. I lost 3rd and 4th gear and the stock 350 is a dog! I want to rip it all out and put in a 6.5L TurboDiesel with a 700R4. I need new drive shafts since i lifted it using Tuff Country's 6" EZ springs front and rear leaving me about an inch short in front and about 3inches in the rear so my T-Case leaks real bad because it does not seal properly (hell everything on it leaks). It also has a set of 35" Mickey Thompson Baja Claw Radials also. So it looks good from the outside with the lift and tires but needs a lot of TLC to get her up and running again. Any suggestions as far as how i should go about getting the swap done? Who should i use? What am i looking at cost wise roughly? Help me out!! Thanks for any feed back i get from you guys. My goal is to have 400hp /400lbft Torque after upgrading the turbo and doing what ever else is needed.
