69 roadrunner, everything brand new including recored 054 radiator, 16lb cap, 180 stat, belts, hoses, mopar performance clutch fan, shroud, etc. The car runs past midway on the gauge and pukes everytime I shut it off. It heats up on the gauge within less than a minute after starting it for the first time. I initially thought my lean condition had something to do with it but I have sorted that out.

My thoughts are defective stat? shop screwed up something when they recored the radiator? cap? maybe something to do with the engine build?

HELP! I am running out of patience with this thing.
