Aftermarket wire harness

[Mauimax3]

Is there anyone out there that may have swapped the stock 5.7 vortec for a simply carbureted 350 or 383 that deleted the wires and or ecm that could pass on what they did. I simply would just like to get rid of everything I don’t need. Not overly concerned about cab or chassis wiring just engine compartment.

Thanks.

Are you running fuel injection or carb?

Carb

You have to keep your ECU to run the transmission or get a standalone controller. You'll need a TPS on the carb if you go that route.

The distributor runs just fine without computer input, but you'll lose some (all?) timing control. Consider swapping in an old large-cap HEI.

I have an HEI on it now... With a 700R..

Then the only thing your computer is controlling is torque converter lockup, and you can replace that function with a vacuum switch.
