you guys have been great helping with this 55 ford. another question, i have a 55 272, i hooked up the heater hose to the factory spot on the intake by the thermostat housing. is there another place to put the probe for the aftermarket temp gauge?

The stock sender location on the driver's side rear of the intake manifold is a good spot, no need to reinvent the wheel. You may need an adapter to make it fit, and be sure the business end of the sender is inserted deep enough but without touching metal.

thanks dobie, i see it now.

got it in and it works great.

Cool beans! Glad I could help..

disagree with dopey,tho the stock location is there,it does not show proper engine temp. water flows threw the block then exits the left head and travels threw the cyl head (MOSTof the water) then exits at therm,combining with left head and out the therm. some truck intakes have sense at therm end where heater outlet is.
heater outlet is the hotest water in the system.  remember the flat heads had 2 sending units 1on each head where water left for the rad.
 i drilled and taped at the front of intake wher heater water is and inst second temp sensor it reads higher than the original location.i think the new location is most accurate as well as monitoring both banks. just food for comments

Ummm. the name's Dobie. I think the stock location was good enough for Henry's engineers. As I said, why reinvent the wheel?

I agree with 2721955meteor on location in front. I wanted to retain the stock gauge as well as a temp sensor for the fuel injection.I too drilled and tapped near the thermostat housing for this purpose.

Spell check?!?
