Gauges

Hello I see that you used the stock gauges on your LS swap I’m in the process of doing a LS swap on my 54 Chevy truck and they told me that I needed ones your look nice can you please help me out on how you did it by the your truck came out nice

Sorry I didn't see this when you posted it, but better late than never I suppose.

The gauges are rebuilt originals from Jim Carter truck parts.

The ammeter is wired just like you'd wire any ammeter into the wiring harness.

The oil pressure comes off of the oil galley just above the oil filter on the LS block. There's an adapter available or you can tap the factory cover for a 1/8" NPT and hook up the factory bourden tube. Here is the commercial adapter............

The water temperature comes off of the back of the cylinder head. I popped out the core plug and made an adapter out of a piece of plate to hold it in. Here is a picture of it



I bought an aluminum bung and welded it to a flat plate that bolts to the back of the passenger cylinder head. The temp probe sits in the hole where the core plug used to be. To seal it, I just RTV'd the plate to the head.

I run a first gen Camaro fuel tank and sender, and to get that to work I grafted the resistor track from an AD truck to the Camaro sender to get the right ohm reading to the AD gauge.



The last part of the puzzle is to get the speedometer to work. I don't have either a mechanical or electrical signal from my transmission, so I'm going to use a device that converts a GPS signal to turning a stepper motor driving a cable at 1000 revolutions per mile
