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.
Just my $0.02...

Thanks for finishing that and some people in Michigan would beg to differ on the total timing for big block wedges ...
