Pulley Diameters

T'stat is a 180* & checked in a pan of water before installed. Lower hose has spring & running a 17" Mopar clutch fan w/ a shroud. 3 core Mopar radiator.

Anything is possible though...it is a Demon LOL :)

I like unedumacated guesses....seems like I'm good at those :BangHead:

So when you underdrive the WP, your WP pulley is larger than the crank pulley correct??

I hate this, but am determined to fix it!!!!

I upgraded my 340 setup with a Griffin 2 row, 1 1/4 cores radiator, Hi - flow 160 t-stat. Never gets above 180 with A/C on. Yes it has a factory 7 1/4 inch single 3 groove crank pulley and the smallest factory water pump pulley I could find.
Good Luck
