if you have any doubts, for a quick and dirty cut up some cardboard to fill in the gaps of that radiator and wrap around the corners of the fans that aren't covered currently so it directs the air THROUGH the fans from the whole radiator. but the trouble I see in that pic is there is an awful lot of real estate not covered by a fan or a shroud, and a shroud to cover all of that is going to look like trash and probably be more of a hindrance than a help. But i'm also not a fan of electric fans for these very reasons. I'm making 500ish hp out of an iron headed big block with a stock radiator, shroud and a mechanical fan and last weekend when the temp was above 90 degrees here the hottest it got was just tickling 200 degrees and that was after a 10 mile steady drive at average 3,000rpm (65ish mph, speedo cable broke) with about the last mile of that pull being probably around 30% grade coming straight up out of the river valley. No need to fix what ain't broke, but there are some guys that know which fans and relays and shrouds and such to use and have good luck with them. And I will add one thing to look at if you still have a/c components in place make sure the condenser is clean and free of bugs and dirt/debris, I've seen many times where even though they aren't hooked up they were hanging out behind that grill dirty and plugged up and that also restricts the air flow through the radiator and the fans.
