Does the water temp. Sensor on the new block different rating. Should it be replaced with the original for correct temp. Reading. The new one on the block reads a little higher on the gauge although there is no overheating. Thanks

The gauge and sender are matched for accurate readings. So best to use the original!

If not get a hold of Willcox Corvette who has just developed a part to get you gauge dialed in....in case you have to change out sensors due to the threads in the heads are different.

I have a ZZ crate engine in my 70 which I installed in early 90's and I used my old original owner 1970's temperature sender and it is still working.
