Re: drill and tap head for temp sender?
I drilled & tapped the head on my suburban. You will need a 37/64" drill bit, 9/16" also works.

Re: drill and tap head for temp sender?
For $18 street and performance makes adapters for this. To me I'll spend that small amount to not risk messing up a head. Just contact them and tell them the thread size and sender length for mechanical gauge. They also make an adapter to replace the oil sender with a mechanical gauge system.

Re: drill and tap head for temp sender?
The adapters are garbage. I drilled and tapped mine on my 6.0 Do it once and do it right. Why deal with leaky cruddy adapters?

Re: drill and tap head for temp sender?
A bit of searching the internet will get the P/N for a sender with the right thread, or you can get a thermostat housing from a later truck with the right size hole.
Just a few alternatives... |

If there are senders that have the right threads and have the right ohm range for the '91 Burb gauges I'm running, I'm all ears...did some searching and found very little info available for stock senders

Re: drill and tap head for temp sender?
When I built my 5.3L S-10, I went to the the auto parts store and bought a new sensor (brass I believe). Then I sanded down the threads enough to run the correct die over it. Once completed, I threaded into the passenger side head and hooked up my sensor wire. Worked for 2 yrs (25k miles) and then sold the truck.

Re: drill and tap head for temp sender?
Sorry, I didn't notice this was in the LS area. I was thinking about the different senders in SBC heads...

Re: drill and tap head for temp sender?
I machined a bunch of SB temp sensors down into a 12mm/1.5 thread so that means NO adapter and NO drilling and tapping the block! Talk about doing it right. If you want one PM me for details. !IF! thats OK with the board? I just need to know which sensor you want because there are like 5 diffrent connector types.

did you drill and tap the head or turn down and tap sender -- I'm wanting to use my stock gauge on a 68.

Re: drill and tap head for temp sender?
the adapter made the temp sensor stick way out and look like crap...... so I tapped my passenger side head.

Re: drill and tap head for temp sender?
CamaroChris,
What year truck is that temp sensor for? I have a 72 and the sensors are 1/2 NPT and I couldn't find any sensors that I could turn down enough to work. Later vehicles use a 3/8 NPT with a different resistance and wil not work with my factory guages.

Re: drill and tap head for temp sender?
The picture I posted is a 91 3/4 ton temp switch. I have also turned down an 86' I'm going junk yard hopping this weekend to grab a bunch of other year temp senders to play with.
