#2 watertemp sensor on 351C engine

I need some advice where to put the water temp sensor when mounting MSD Atomic EFI on my 351(now418)C engine. I planned to keep the old sensor on the block next to the thermostat (if possible)since the stock tempgauge (in my 71`Mach)seems to work just fine. I am also curious of Your experience with the MSD unit. The proform 850 will soon be resting on the shelf and I hope to get some better mileage since gas is rather expensive round here..

Thanks. Arne.

For my MSD system I put the MSD sensor on the block for a more accurate engine temp reading. I put the OEM sensor on the water pump. There is a removable plug there with the same threads so its a quick change. The OEM water temp connector is also long enough for the new location. This set up worked very well for me.

Just to add on my build thread you can see the location of the OEM sensor. Just below the MSD black connector you can see the new brass temp sensor on the water pump. They are real close to each other.

It was so close that I didn't see it...Thanks.

Do You run a fuel system with or without a returnline and regulator?
