Thanks for all the support and good wishes guys! This forum has been a great support group to help me stay motivated!

so, driving to work this morning... temp gauge runs about halfway up, when in 5th at 60 or 65. If I shift to 6th and lope along at 60 or 65, the temp creeps up, to at least 3/4 of the way up. I only can conclude that this means theres an rpm dependent issue. Is it possible there's still an air bubble in the system causing this issue? Not sure what else to look at to determine why an rpm dependent cooling issue would be present. water pump was new on the motor btw.

I believe that is typical. Both my '91's ran that way.

John, thanks for that info. I don,t recall the car running like that with the old motor; I did put in a new temp sensor so perhaps this is more accurate, and the old one was "lazy"?, not showing accurate readings? Car seems to be running well, but clearly runs hotter in any gear if I am not turning at least 2300 rpm or so.

unless you have a chip with reconfigured fan call in temps, then yes I do believe your readings are normal. The only exception i can think of is i always takes me a couple of engine heat cycles and an over night sit to get the proper coolant level. I usually end up having to put almost a quart into the overflow bottle the next morning.

my chip is a haibeck chip, burned for secondary delete among the usual mods. same chip as I ran w. old motor... plus, fan should be a non-issue at highway speeds...

Hoping it's just an air bubble, or the change in sensor, as mentioned!

Water pump likes 2k rpm.
Check it in traffic if your standing idle just rev it to 2k and you will notice temp come down.

is your temp sensor a factory one or one from a parts store . i got one from a parts store and had the same problem .but when o hooked up my scan tool found that 1/2 way up was now 180 degrees and 3/4 was about 195 .
