My 1972 Dodge Dart

leaving the t-stat out is really not an option!! Not every case but most cases leaving the t-stat out can make your over heating worse !! The reason is the coolant is moving to fast thru the radiator to cool down appropriately!! Just a thought to put out there !!

I appreciate the warning, I've heard the same, but even still i did remove the stat today to see if it helps. With old or stock sized radiators the fluid can cycle quick enough to not cool, but I'm banking that my 3 row over sized Griffin radiator is big enough that even without the stat it'll have enough vol to cool. If not it'll go back in.
