Help cooling 408 stroker

I have a 3 core Champion radiator with their two 12" fan kits and my 408 runs in the 200-210 range pretty regularly. I have the early version where they used the crap Chinese eBay fans. Now their kits are offered with the 12" Spal fan upgrade which is a HUGE CFM difference. I'm going to try and change out my fans and see if I can't keep the temps under 200 degrees.
