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...
Is this correct ? That would only be 25 TOTAL, I can see it running even hotter ?????
10 degrees in the distributor is x2 @ the crank + 15 degrees (initial).. 20 + 15=35 degrees total @ the crank. IMHO... One can run a little more total advance but the BB wedges don't really run that much better with more advance.
