  1. 94-98 Powertrain
    Hi everyone. I have a 1971 Dodge W300 with a '94 12 Valve and P-Pump. I just put in the 3K gov springs, got the whole job complete installed everything to the correct specs and things went well at first. Drove around the block and the power increase was phenomenal. Went to take it on the freeway...
  2. 98.5-02 Powertrain
    I have a 98.5 engine with 24 valves. I converted the injection pump to a VE pump from a 91. Also I put the 91 camshaft and a manual supply pump. So it is basically a 165hp 91 model 12 valve but with 24 valves. And I want maximum fuel economy not black smoke. So my question is, what...

    I have a 1995 2500 12 valve 2wd that I just installed a lock up switch that keeps blowing #9 fuse which keeps shutting off my motor.

    sorry for the bad photo but it’s the best I could find for the electric plug. I was pulling my motor out and I didn’t see this plug and pulled just the wires out of the plug. Any idea what this plug is called so I can order a new one with some wires on it. Thank you in advance.
  5. 94-98 Non-Powertrain
    I have a 94 12 valve automatic with afc live, 3k governor springs and a new fuel pump. Before the modifications until current after an hour or so of driving it will buck and shudder then the throttle will kind of stick for a second and it will die. After it sits for a few minutes it will drive...

  7. 89-93 Non-Powertrain
    I want to know how I'm getting such lousy MPG. My truck is a 91 N.I. 727 4x4 stock height & suspension. 10 mpg cannot be right. Current mods - fuel pin, recently installed 366 spring last weekend and reset the power screw to its factory setting (counted the threads). Truck does have a leaky VE...

    In a couple months I plan on doing a 12 valve Cummins swap on my 2005 Ford F-350 and I’m trying to figure out the fans. I’ll be getting a new mishimoto radiator and inter cooler and all. I like the idea of having more room infront of the engine and the little horsepower and mileage gain of the...

    I just got a 90 model non intercooled 12 valve donor truck. I had to get a new lift pump to get it started. Once i got it started it immediately tried to runaway/overfuel but i can kill it with the fss. I havent let it go for more than 5 seconds before killing it. I back the power screw out 3...
  10. 94-98 Powertrain
    I have been battling this problem for awhile now.. I guess my question is, If I have the motor at tdc should I be able to see the timing tooth in the ppump if set at 18 degrees advanced? Cause I’m not seeing it in the hole at tdc
  11. New England
    Hey everyone, I’m new here and I have a couple of cummins, I have this 1993, a 2003 and a 2005. I have seen a lot of 1990s trucks similar to this one go for some pretty large sums of money and am not really sure how to price it for sale. I’ve seen many in the 10-15,000 range, and I’ve seen a...
  12. 89-93 Powertrain
    Hello all, i have a 1993 d150 in decent shape and a 1993 d250 that the frame is a bit rough. I'm wondering if I could switch all the d250 components including the 12v cummins, both axles, all wiring etc. I'm aware the d150 frame is 6 inch and the d250 frame is 7. I'm wondering if the half ton...
  13. 94-98 Powertrain
    Hello, I just purchased a 2014 12v with a vp44 pump. The engine only had 80k miles but I want to change it over to a p pump. Any suggestions on converting this 12v back to its original glory days? Will any p pump work? I’m also installing this engine into a 99 f350 with a 6 speed. Any advice...
  14. 94-98 Powertrain
    So I bought my first diesel, a 1994 12 valve 4x4 today. I'm wondering what the best additives to use for fuel mileage are? I know that 2 stroke oil helps, but how much per tank, and does it matter if it's premium or not? Grateful for any help, thanks.
  15. 94-98 Powertrain
    Good morning, I've got a 1997 3/4 ton 12 valve 4x4 5 speed with 350,000 miles and counting. I'm pretty familiar with most of the free mods (AFC, P-pump work, boost elbow, etc) and would like some advice on a few other fixes. Truck was bone stock when I got it a few years ago. Since then I've...
