200R4 Swap ?

[TobyArnot]

Hello group,

Anyone know what's involved in putting a 200R4 in a '70 C-10? I've only had the truck a few "hot" weeks and still working on a battle plan. The turbo 350 has sprung a few leaks and my first thought was OD. Truck has a factory 3.73 posi rear. Really don't want to lose that! Have a few parts on the way and would like to get on the road soon. Pretty sure I'm going with a 2-1/4 dropped disc brake non-power conversion. A 2" block in the rear. Have a few goodies on the way and looking for a break in the weather. My old ticker won't go much in the heat and humidity.
