3406E Wiring Vs. 3406B

If you decide to do a swap and have any questions just shoot me a pm.

 

This is a great post as I too am lik MRbeast looking for a older truck and I didnt think about the c 12 thing but thats a great idea

 

Just thinking can you do a swap from detroit to cat?

 

Yes thats what im thinking get one with a detroit in it and swap for a cat .and yes before it goes on the road a complete out of frame unless i find one that has been done by a cat shop....

 

Most of the time a guy stumbles across a good deal on a truck that would be a prime candidate for installing a powertrain of your choice. Then, you find a good deal on a engine or trans or a combo that a person would love to use for a good deal not realizing that little things like accessories on the engine, A/C pump configuration (style,mounting(location), fittings) different size, shape, location of the water pump inlet, oil pan configuration, front motor mount offset, turbo location (low,mid,high mount), and flywheel housing all add up to a considerable increase in the cost of the project. As far as the motor mounts go, a guy could for example could have bought an older 379 pete only to find out that the killer deal he scored on the engine came with the straight mount flywheel hsg instead of the slanted mount flywhl hsg that peterbilt used for a number of years now and are readily available. If cost is a factor, it is alot easier to build a set of motor mounts than most people realize. No matter what a person does, somethings to look out for are:

1: fan hub height and distance to radiator
2: height of engine-distance from suspension to suspension stops is greater than distance from axle to oil pan

3: angle of engine
4: clearance between the back of the cylinder head and firewall (depends on chassis and engine make)

5: turbo-if it's mounted high or low and the outlet elbow may need to upright or rotated down to work with air to air cooler

6: clutch linkage
7:transmision top cover-front or rear mount
8: driveline length

As far as electronics go, there's no comparison to using a stand alone engine control harness for no matter what conversion a person might entertain. If you spend a little extra time and take in consideration some of the things i have mentioned here, alot of the headaches, mystery, and cost associated with doing conversions like these ease up considerably. Thought i might be able to add some insight, i hope this helps with some questions you might have.

 

Thanks and yes they are great thoughts to look at and if any thing else hits you let us know
