Hey guys! I'm building up a K5, and will soon have a mechanically injected `93 6.5TD available coming from a truck I am buying for the NV4500 I'm stabbing into my 3/4 ton. While the 6.5 does need some work (could be simple, could be spicy, don't really know till I get the 1 ton), I'm thinkin I'll put it into the K5. The K5 was originally a 6.2 diesel truck, and already has all the wiring under the dash intact, the diesel rad / core support, hydroboost etc. I'd just need to build / buy an engine harness, then wash out the fuel lines to get it running Anyways, I'm planning on running a 4" lift with 52" springs up front, 63" out back, and 33" tires, with 4.10 3/4 ton diffs, detroit locker in the 14 bolt, but I'm still debating on what to do with the transmission. The two options in my mind is either a TH350 / 700r4, since neither needs a vaccum signal, or an NV3500 / SM465. Which would you guys go with? The truck is not a mud bogger (though it is sometimes unavoidable, if you know what I mean ), but is going to be a trail runner, that goes slow over some pretty steep terrain. I just see the diesel as the best option as it'll run at any angle, will idle up most anything, doesn't have any electronic ignition components to fail if they get wet, better for the environment, and better on fuel too. Not to mention having that cool factor, esspecially with a straight pipe off the turbo What do you guys think?
