thanks man!

Got everything installed, checked, and double checked this afternoon. Put in new spark plugs and the distributor timing was set to match the hyperspark and all that needed to be done also. Got it up to temp and checked timing and static-timing. Also, no leaks of anything, so I am happy about that. Took some time to redo some of the wiring that got moved around during the disassembly. Things at the back of the firewall are much neater, and I am happy about that. Oil pressure if great (still high, but that's been discussed on and off for many months now) and the relocated oil pressure sender makes me happy. All in all, successful project, and it would have needed to be taken care of sooner or later because that coolant leak could have started dumping coolant into the engine without me knowing, so I am glad that this was tackled now. It was too rainy here to do a test drive, but I will do it tomorrow. Did a datalog while the engine warmed up and fiddling with the timing stuff. Will also change the oil and filter tomorrow, and hopefully if the test drive is good, will get the car setup for drag racing Test and Tune this Friday night at Island Dragway.

Recap with question: Just this past week I relocated my Holley Sniper's coolant temperature sensor. It used to be right in the intake manifold next to the thermostat housing and was very unsightly. I cut the wire and extended it, allowing the CTS to now be mounted in the coolant port that is on the passenger cylinder head between cylinder 6 and 8. I then put a pipe-plug at the hole in the manifold and I am very happy with the look.

I expected to read higher coolant temps, but now that I am visually seeing the higher temp numbers on my sniper's display, I am getting curious. Typically I was used to seeing 178-185 at the sensor when it was at the top of the intake by the thermostat. Now I am seeing 225-235. I used my temp gun to check the block, heads, manifold, and the temp gun confirms my 230 reading at the head, as well as the 175 number that is still at the pipe plug area at the intake manifold.

So, in short, the engine is running exactly the same, but I am wondering if these higher CTS values are now something I need to consider during changes to my tune files. What do I need to change immediately, and what should I keep an eye on and adjust later????
