New to forum 1981 C10
« on: July 21, 2019, 08:49:43 AM »
Hello everyone, glad to of joined seen plenty of info as it is. But Iíve got a few things I would to discuss with others about my project. Itís a 1981 C10 it had a 5.3/4L60E swap from a 2004 Silverado put in. Engine and trans all bolted up as well as driveshaft all thatís left is all the wiring and bolting on some of the engine parts and accessories.

My question is I found a hole at the rear of the intake completely open. Not sure what it is, and the intake sounds like thereís water in there, thought about cleaning it with something but being plastic not sure what to use, would degreaser be fine? Donít want to ruin any sensors there. I also have the electronic pedal would it be best to swap that to cable throttle body or is it straight through to just throw on the pedal and sensor in stock location of the current throttle pedal?

Iíve got quite the work ahead of me. Luckily a friend is good with tuning and etc, and he will help just make a whole new harness for it from scratch.


Ac is another topic, I had seen it was the R4 so I thought of just getting the brackets to run it but itís an R4 V-belt that sat on the drivers side, so I donít know what to if I should mix it with a system from a 87-90 pickup tbi engine or run the sanden etc.

Any suggestions or advice would be appreciated. Iíve had several square bodies but this is my first LS swap one.

Alright so figured out the hole! Itís cam sensor. Ordered that. Got the alternator and maf in my cart ready. Will be doing harness soon.

Have another question, I have an external fuel pump regulator kit for the swap, but the truck has dual tanks and apparently they worked. Anyone keep them going? Iíd imagine fuel pump would just have to sit in front of where the fuel selector is.


One more question, what do I do with this vacuum line that has a green cap? Canít seem to find the same setup on the pictures of swaps Iíve seen. As you can see the tubing is kinked and cut ooff toward end where it turns to a metal pipe.

Parts are slowly starting to come in. Soon I will make time to get started on it. I was able to move it to my back yard this weekend and threw a cover on it. I noticed that camshaft hole sensor might of been a perfect spot for water to go in considering the firewall where the cowl ends is shot and has holes. Whatever water collected in the cowl probably made its way into there. And I was right checked the oil and itís a tiny bit thick and light colored as if it had some water. Not too much though. Any recommendations on the procedure for that? Should I run a mystery oil or something on first crank then drain and change it again(so technically three oil changes). Itís so bad I couldnít even put cam sensor in even with some oil on the packing. I pulled it back out and the tip had rust debris. This is gonna be interesting!!



Thatís the one I ordered...donít see any different configurations so Iím hoping it will go in, unless maybe they broke the end on it and the tip is stuck in there.
