I am still in the process of putting new heads on my 350. After i got both heads put on, torqued down to 65 ft. lbs, and my intake torqued down, i noticed that i put the wrong head on the wrong side. While i know that SBC heads are identical for either side, one of my heads had a plug in the tempertuare sending unit hole, and i put it on the driver's side, and the head w/o the plug on the passenger side. The plug has proably been in the head since it was casted in 1969 or 1970, and i tried to get it out with no luck. So, it looks like i am without a place to put my temp sending unit. I notcied that my intake manifold had a plug in it going into the coolant passages. Could i remove the plug and put it in the intake? I would simply put the sending unit on the passenger side head, but my temp. guage is mechanical, and the wire won't reach that far, but i think it will reach to the intake.

Thanks for any help.

You can put it there but it will read a little cooler than it would on the head.

i always purposely switch the heads.. the sunpro gauges will reach fine to the other side... i do it so i can hide the wire behind the engine

I have el-cheapo Equs guages. They work pretty good though. I just rememberd, i may have a little extra line coiled up underneath the dash....maybe it will reach. Will the sending unit hit the headers on the passenger side?

You can run it in the intake with no problems. It just won't look the best IMO. Have you tried to run the wire around the back side of the block to see if it will fit? Just asking...

Have you tried using a weatherhead socket on that plug? If you can get the right socket on there, it'll come out 99% of the time.
