lots of great suggestions above and i'll share the sentiment of keeping it factory. the factory "bubble top" radiator and shroud with a clutch fan is a tough combo to beat.
i understand if you don't wanna splash the cash for a new waterpump, but the flow cooler unit is a very nice piece and well worth the loot.
get a *good* t-stat, not some parts store junk or something labeled "race" or some such nonsense.
i've run that set up for the past 25+ years and it'll pound the pavement at 100mph thru texas in august and not break a sweat; and sit idling in LA traffic on a 110* day just cool as a cucumber.
ETA: you're going to need to lose that adapter you have on the bypass coming out of the pump. it's way too tall and you won't make the turn going into the manifold without kinking it.
