Is the plug behind the hose at the top rear of the head engine coolant or oil passage? Need a place to install an engine coolant temperature sensor for TBI ecm. Thanks Carbking. I kind of like making everything in my life more complicated than necessary. If I don't like the single 2 barrel TBI, I'm going to try 2 1 barrel TBI's . If that doesn't do it for me, I'll do the small 2 barrel Holley. Jim
