cummins big cam 4 cpl:749 beige paint NTC315 hot rodding questions. low flow to high

View attachment 80146 I didn't get a clear photo of that casting number! I'm gonna have to drive back to where my truck is parked and figure out how to get the picture and make the numbers clear. Mine are kinda rusty. Know any tricks? Maybe I could try to fit a wire brush in there???

 

I didn't get a good photo of those exact number!i will have to go back over to where the truck is located and get the photo. My numbers are very rusty. Maybe a wire brush would help?

 

Grrrr. I didn't get a good photo and my numbers are rusty! View attachment 80148

 

Here is a shot of my truck engine from the turbo side. How can I determine if I have a radiator type that can be converted from low flow to high flow by removing baffle plates?

I am basically intersted in the tips and trick to this engine because I use it as a lowboy in the mountains. I need to pull hills at the speed limit to keep traffic from piling up behind me and panicking. It actually can be for safety. I'm not truck pulling. But when I go borrow a detach with all the goodies.....it gets heavier. And I compare how weak my truck is to the 6nz cat trucks I drive with hop ups. I want something close to that power but those guys with those trucks.....constant money and expense. I don't use my truck all day everyday. Once or twice a week to move. I don't need that cost. A 379 Pete with that motor....expensive......

 

I can't decipher this. I have wire brushed it and its rusty! Can anyone figure this turbo exhaust housing number out?

The bottom left number look like 26? So maybe mine is a 26 mm?
