Mechanical water temp gauge on 69 350

I have the original 350 in my 69, and it has an electrical sending unit for the water temp (for the gauges in the console). I would like to install a mechanical one, but can't for the life of me figure out where it could go. It has a 70 LT-1 intake that does has a plugged off hole in the very front of the manifold, but don't know if it will work there. Any suggestions?

Depends upon the length of the sensor at the end of the Bourdon tube, manifold may not be deep enough. I would try at the pass side head between Cyl's 6 & 8.

Autometer has an extension fitting that will work in the manifold if the length of the Bourdon tube is an issue. The extension fitting will also work in the cylinder head if needed.

Mat ?I ask , why do you want to run a mechanical instead of an electical?

Well, I have the console gauges, but always felt more confident with the accuracy of mechanical gauges. Opinions?

Re: Mechanical water temp gauge on 69 350

Just my opinion...Personally I think choice is a personal preference...
I much prefer electical
1/ less risk of leak due to long term vibtation rubbing
2/Electrical is very fast response when things go wrong...saying that I also run idoit lights.
3/Install and maintance far easier
4/When something goes wrong with electrical it either doesnt read or reads super hot..broken wire or short, or know the sensor is stuffed

A note on installing sensor in head or manifold...
There is stuff all diff between the 2 locations....but in the head one gets temps come up very fast on cold start because the thermostat hasnt opened, where as in the manifold one can see the thermostat open.
Routing the loom from the fender to head...I extended, sliped my loom up under the fender, and run the temp wire along the bottom of the top radiator hose, hidden away.

I chose electric, basically because you usually need to drill a hole in the firewall big enough to throw a cat through for the mech type.

Re: Mechanical water temp gauge on 69 350

I have since switched to factory console gauges on my 69 but when I had a mechanical temp gauge I took of the cover on my firewall where the cluch would have been (I have an Automatic). I drilled a hole in that plate and put temp line through there with rubber grommett. Then if I got rid of mechanical line I would just need a new plate rather then having a hole forever in my firewall. Just an idea??

True... I made a rubber grommet to fit the hole out of a larger one and put it in the clutch hole plate just like MTN10 did. I just split the grommet and 'adjusted' it's diameter until it fit the hole perfectly.
But when I want to move my gauges or need to pull the water temp gauge, it's gotta come through that hole in the firewall again!! What a pain... and the grommet is hidden under the master\booster.

I have both hooked up... sensor in the drivers head along with a mechanical gauge. The idiot light isn't really needed because I keep my eye on the gauge instead. But if it ever gets hot enough to shine at me, I peek at the gauge and watch it raise and lower.
