Detroit 60 Series

I would go mechanical engine on a rat rod. 2 wires to hide. Probly find an old runner cheaper too. An ecm should not be in the same sentience as rat rod.

 

I don't a one ton frame would hold up to the motor. You could run a l10 cummins or a 3306 cat if you wanteed mechanical but not a 15l engine. An allison 750mt I believe is the size will bolt directly to either motor or even the 60 series. Its a non electronic 4 speed automatic

 

Is that all I have!!?? On my 1988 Cummins 855? Just 2 wires!?

 

Well I was being a little silly but nothing like a 60 series. Rat rods are all about simplicity.

 

Speaking of this setup you listed,here's a cat motor in a gm 1 ton with the same transmission.http://www.trucktrend.com/features/...owing-king-with-7-2l-caterpillar-engine-swap/

 

That's a 7.2 aka 3126, literally half the size and weight of a series 60, sticking a series 60 or any big block on a 1 ton frame is like sticking that 7.2 on a Geo Metro, there's a guy in Kalifornia with an F150 with a N14 and it seats on the bed behind the cab, he did reinforced the frame and still looks heavy the way it moves around.

 

If you want old skool, look at a 3208 Cat. Miniature version of the beastly 3408.

 

That's what I'm talking about!!!

 

Assuming a DDEC III or Non EGR DDEC IV, it's pretty simple. They have a separate ECM power harness that you just need to hook to fused battery powers and grounds. The engine sensor and injector harness will stay as is. They have a separate data link plug that you'll need to wire to a diagnostic port taken from the donor truck.

The most wiring you'll need to do is in the ECM OEM harness. This is where you'll find ignition power, throttle position sensor (you'll need the correct one), vehicle speed sensor, coolant level sensor, jake switches, cruise control switches, clutch switch, etc. The ECM pin out is easy to get and just a matter of wiring everything up.
