Mine is in the driver's side head. Also the '92 454 has it in the driver's side head.

Mines in the intake next to the thermo housing.

What's the difference in temperature readings between these 2 areas?
(not meaning to hijack the thread)

Drivers side head is where the stock location is. That's where mine is.

+1 on the driver's side head for a normal flow Chevy V8 engine. On a reverse flow engine (like the 90s LT1), it went on the passenger side head.
You can also put it in the water pump or intake bung as others suggested. You might get a more consistent reading there since the heads do heat soak (and sometimes cars with EFI use two different sensors for this reason). If you are using EFI, and need a probe for the computer, I'd say use the WP or intake. If you are hooking up a gauge, I'd say put it in the head. A head will heat up very fast if there is a cooling issue and it will also show up on the gauge faster to warn you.

Reverse flow is only applicable to the '92-97 Corvette (and '94-96 B/D-Body) LT1 engine. On these motors, the WP was driven from the cam, and it pushed water through the heads first. It's actually a neat system. There are lots of details online about this, one link being: http://sstilletto.tripod.com/sstilletto/id11.html Though now that I think about it, I'm not sure it matters which side head you put the temp sensor on.

Re: Pics of where the best place to install a temp gauge on a 350?
If my heads not have the ports to install the temp guage and now I am going to use the port on the intake, next 2 the thermostate for an eletric fan where can I put he probe for mecahnical temp guage. Or since the eletric fan has two probes can i split one to hook up a eletric temp guage.

in the head, left or right, is the best place to put it.
If hooking a fan controller, in the rad is the best place for it. |

Re: Pics of where the best place to install a temp gauge on a 350?
if worried about engine temps....you could also add an oil temp gauge to get a better view into your motors internal temp. Mine doesn't have one now, but will one day when I finish the interior.

Re: Pics of where the best place to install a temp gauge on a 350?
my stock gauge sender is in the drivers head. i just added a mech. gauge (had it already)in the thermo housing. it gives me a nice indication of the status of the cooling process or the temp. of the water coming out of the radiator. after i have it there a while i'll move it to the more standard location the intake mani. right now it seems that the stock gauge reads right on.

Re: Pics of where the best place to install a temp gauge on a 350?
I had mine in drivers side head and moved it to the passenger side head to allow for putting a second sending unit for my dual electric fans. When I placed temp gauge in passenger side head the temp reading was at least 30 degrees hotter compared to the reading when gauge was in drivers side head. Everything was exactly the same except temp reading. I am not positive but I am hoping the difference was due to the fact as the water circulates through engine and heads it heats up so when it gets to the gauge port on drivers side head it has soaked up a bunch of heat causing the difference in temp reading between the to ports. Can someone please tell me if this is correct or do I have another problem all together.
