Quote: What about the distributor and timing curve... A close friend and his 383 was overheating badly up to 225, he changed water pumps, added a shroud... Still a problem... I checked his Mopar performance distributor, he had 14 degrees mechanical advance...
I reset it to 10 degrees mechanical advance, set initial @ 15 degrees and fired it up.. It ran @ 190 degrees and is doing very well in our 105 degree SoCal heat wave..
Check the basics... Mopar built a pretty robust engine and cooling system..
Just my $0.02...
Good point and easy to check, I will definitely check that out, thank you.
