That NP435 is a HD 1:1 final drive trans, with, as you have found out, an extremely low non-synchronized first gear. That is a grain-truck trans, suitable for hauling heavy loads over soft dirt fields. However, the other gears are not that bad and, the 1/1 final is the same as any other manual...

I would be leaning towards either a fuel-pressure issue, or a failing EGR system. A scanner should reveal the problem, but without a code, you will likely need a good EFI technician to decipher the results. The fuel-pressure issue could be as simple as the pump sucking air.

Ok thanks

Can that even be successfully done? I thought they were different spline counts, and then there is the pilot to deal with.

my big fat mouth has cost me a lotta money over the years. If I said I would do it, I had to do it. I'm a lot more careful what I say now. Actually, I learned to think things thru a lil better; "let your yes be yes and yur no be no"; I learned to say no.

ouch:(

Would it be easier to swap cabs and boxes? Well I guess not. Those are both fuel injected right

Nice looking truck I had a 92 Dakota with an overdrive.

I had a 92 Dakota extended-cab longbox with a 5.2/overdrive ,4x4, and 3.91s. I crashed it into a guardrail on glare-ice. I miss it a lot. 65 was ~2100

Those old trucks are huge and heavy bricks and they take power to push thru the air, and the faster you go, the worse it gets. So if you really want one of those, you are gonna have to figure out how to make it take less power to push it thru the air. Here is some help; the rule of thumb is that...

those are awesome looking trucks. And 390s are pretty good engines too.

You know what would help, is if you could list all your pertinent info, in your signature, so it appears on the bottom of every single post. To do that go to the top of any page and find your name on the Top RH corner, clik on it and go down to "signature", then clik on that. Down will drop a...

Charm, yur not listening. The vacuum advance does not work at WOT, there is not enough manifold vacuum to make it work. And it MUST not work at idle. Because as soon as you step on the pedal, the vacuum will drop out, and your timing will go retarded. That device must only work at Part Throttle...

WOT power timing is done without, without, without vacuum advance; as is the idle-timing; as are all timings.The Vcan timing is never considered part of the timing. It is purely a PartThrottle device to dole out advance in accordance to the load, to increase PT Torque, which helps increase PT...

OK gotcha with the electric choke; but the bottom line is still the same; the valves have to close all the way, by backing out the speed screw. I have never seen a carb on a Mopar, that could not be closed all the way; don't forget the secondary link rod; it may have to be rebent; that is why it...
