its about 180-185...

my 02 lb7 was running cold at 160-165.. had to replace both thermostats..

when running a hot tune u should be runnin in the 180's or higher.. better on the engine..

In the OK summer mine runs 200 (one mark below 210). Here lately it's been cooler and it doesn't get above the first quarter mark unless I run it hard.

I live in AZ and my gauge was reading like 205* so i got worried about it and bought a Edge Juice with Attitude and the Edge moniter tells me it is running 189* while the temp gauge on the dash reads like 205*

my Edge tells me im running 175-200 most of the time, this time of year im seeing 180 most of the time

and agreed that the factory temp gauge is worthless, only really good as a dummy gauge....tonight my gauge said 180 and edge said 160 while i was still getting warmed up
