Put a a Flow Kooler on my small block stroker aluminum heads. Its been on there for 15 years now lots of high RPM pulls. Recored 3 row original radiator (factory AC car), mopar performance clutch fan, high flow thermostat. I can sit in traffic with AC on in 100 degree heat no problem at all.
And yet, there are COUNTLESS threads here advising guys with over heating problems to fix their junk up like yours and it falls on deaf ears. You just caint tell um.
