Quote from: Eyez Open on April 24, 2023, 12:19 AMYour advance is great at 2650 rpm...I'm shocked GM got that aggressive.. actually for GM that is aggressive.
Your temp is quite high for my tastes, 170/185 tops under most conditions. Bear in mind that is my opinion only a few things about temperature. Readings taken near the exhaust port will run 8/10 higher than temps taken from the intake manifold.
