We have found often the cooling problems are related to incorrect ignition timing and/or lean fuel mixture.
IMHO.. Today it is difficult to find an experienced mechanic that will take the time to diagnose and correct that doesn't cost major $$...

Just my $0.02... wink


Yes, I went through this with the 383 in my 69 GTS. Typical .509 cam, Torker intake, Carter 650, MP electronic ignition on a stock bottom end. Had overheating problems like crazy, threw everything I could on it, radiator, fans, pulley's, shrouds, and it ended up being to lean and too much timing! This was in 1981, so these kinds of things have been going on for decades... wave

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
