5.9l Cummins swap into a lucky Square Body

Well that sounds right. Both ports come off the oil filter plate. Did your engine come with a long flex tube that connects the end of it with the oil pressure switch? Mine did and every time the switch would lie against something metal it would ground out and do that. Only other thought I may have is if you changed the awg of wire changing resistance but it shouldn't be that significant.

No I just plug it straight in to the hole next to the feed line for the turbo . I don't know what it's doing that maby I need to put it on a line ? I was thinking about moving it some where else or get a nother switch it a new Switch but still good be bad I guess

The second port beside the turbo feed is where it belongs. The flex line is because the vibration of a cummins will bust off the end of the sensor.

I'm already seeing a diesel gel problem here. A block heater will help a little but you're prolly gonna need to use some additives in your fuel in the winter huh??? Even at 25 degrees in the middle of the night, This Cat in the C6500 doesn't like to start. The Cummins in the Peterbuilt is not to bad at 25, but in the teens it's a bitch too.

I'd consider two block heaters (the stock heater and one in the lower radiator hose), a fuel line heater, and keeping that grid heater (hopefully its still there) at -12. Turning your fuel pump up and timing advance will increase power but make cold starts worse. Keep that in mind.

Does anyone know if you can run a GM SM465 4 speed tranny with a 6bt? I read somewhere that you can on a 4bt and you can run it on a 6 but youll chew up clutches like crazy.

I'd imagine it can be adapted and had been adapted. BUT, I sure think being diesel, I'd want to go with a NV4500. Diesel like LOW rpm's. OD will be good for a 6BT and mpg even moreso than a gas engine.

I was planning on running a Dodge or GM NV4500 from the start but I was just trying to see if I could save some money.

Does the NV4500 use a larger clutch? If not, I don't see why it would make a difference.

If I could find where I read that id post it, but I can't find it.

Pulled a couple threads you might be interested in. I know southbend and valair do custom flywheel clutch setups and can handle enough torque to pull a house down. Give them a call. Do not try to buy a pre 96 chevy nv4500 for a cummins. The input is not interchangeable with the dodge version and this will have to be done if that is the tranny you want.

Get yourself an overdrive the first time. I got on one of those online calculators and if you have 3.08 gears with 33's you will be turning 2030 rpms at 65. That engine redlines at 2500. You'll hate it. It's sweet spot for highway cruising is 1700-1800.
