    NP203 to NP208 swap?

    I never knew that twin sticking a 203 was a thing. That's my only issue with it, fulltime 4wd. Might have a change of plans here. Hmm

    Np203 part time conversion?

    It's odd how they put lower gears in the older nonoverdrive rigs and higher gears in the overdrive rigs.

    Np203 part time conversion?

    mine is full time with locking hubs. I averaged 10-11 on my trip. Included mountains. That's what I call indicated mileage. With the tires on it I'm off 12 - 14 per cent on the speedo. So the actual mileage is either higher or lower lol. Its confusing lol. Mine has a 400 in it. Needs...

    NP203 to NP208 swap?

    I like being able to use 2wd, vs 4wd with an unlocked axle. It is a tank though, never heard of one breaking.

    NP203 to NP208 swap?

    208 is a good t/c. Drive it with some common sense and it will last. It was good enough for the Armys CUCVs. I have another truck getting a nv4500 and new motor. It'll have a 208 behind it.

    NP203 to NP208 swap?

    I have a 79 K5 with a th350 and 208. It has manual hubs but still only gets 10 mpg. I bought a 208 for it. It's my springtime project. Th 350 & 700r4 both have 27 spline output shafts. A 208 from a 1/2 ton will work fine. Driveshaft, you'll find out when you get there.

    Tools for trip

    you'll be fine. Bought my 79 just jan. Drove a rental out, drove it back. 2200 miles. Spent an hour at the first auto zone I saw, checking it over. Topped off all fluids, replaced all burnt bulbs bought extra fluids (oil, trans, coolant and a can of freon for the defroster to work properly). As...

    How to Calculate Gear Ratio wo Removing Covers

    Mine works also, but it's 14% off due to the increased tire size. Taller tires effectively raise (numerically lower) the gear ratio. The average thought is .1 ratio per 1 inch of tire size. For example, 4 inch taller tires with a 4:10 ratio effectively becomes a 3:70.

    7.3 Powerstroke swap

    Yeah, you're right. Shame they quit making the P400. Would have loved to see them cycle through the surplus system. Hell, ol Leroy Diesel put a new one in his rig. He sells stuff for 6.2/6.5l diesels. They still me new Optimizer 6.5l's, but hell both of my Suburbans aren't worth that kind of...

    How to Calculate Gear Ratio wo Removing Covers

    got a tach? You can use a rpm/gear ratio calculator, enter your speed (I use a GPS speedo app for accuracy since I have larger tires), and your r.p.ms to calculate your gear ratio. I use the one on grim jeeper. http://www.grimmjeeper.com/gears.html
