[Irish Wake1011]

Hi On the cylinder head I have the gauge sensor and a fitting for a heater hose I don't see anyplace to install the holley sensor
Where are you guys installing it
TIA

A lot of the sniper installs have been using the block drain on the drivers side.

Like @Jdc1 mentions, I installed mine into the block drain location.

I’m getting about a 10* difference in temp between the block sender and the dakota sender in the head.

Block drain. Good time to clean that area out as well.

With the sensor there, what kind of temp readings are you getting while running? Thanks

Normal days: 187 - 192
Hot-hot days: 187 - 202

This photo was taken back in April, right after a 325 mile trip from Woodstock, GA to Santa Rosa Beach, FL. The max temp I read was about 197 on the way down, but quickly cooled off....I did read 202 on the way back, but it was a HOT day and was only over 200 for a minute or two.

Anyone know the 2f engine displacement? Thanks

Anyone know the 2f engine displacement? Thanks

FWIW: I'm putting this here for future reference. 2F engine displacement calculated at 258 cubic inches.

Can you tee into an existing coolant sender fitting on your 1F head? The block will take a lot longer to warm up....

From a 3 day hibernation, this pic taken about 2-1/2 miles from my house this morning.

And this pic was taken about another mile down the road.

"HERE" is some more discussion on this.

Yes you can but you will need some adapters and a brass tee. I can get a pic if you need it.
