Thinking of switching the coolant temp sensor to passenger rear vs drivers front.

[dabuickman]

I have a new LS 3 495hp on order. Should be in a few days.
It’s going into my chevelle and I was wondering if there is anyone that has moved their temp sensor to the passengers side rear on the head. It would be a cleaner install.
But want to know if it will read hotter since it’s farther away. Looking for real world experience
Thanks

I run my temp sensor in the passenger side rear of the head. (Ls7 converted to wet sump) No issues with it and don't have a comparison temp but I would think the reading will be slightly higher than at the front of the engine. Possibly a little more accurate?

My LS7 swap my ecm picks up temp at front of driver side head. My old school stewart warner gauges pick it up passenger rear of head.
My stewart warners consistently read about 5-10 degrees higher than the ecm

Ok
So it looks like a ten degree difference between the front and rear. Makes sense I guess
Thanks for the info guys

The rear is hotter. That's why on my 400 blocks I ran a bypass line front to back on the intake to help balance cylinder temperatures.
