Best aluminum replacement radiator for 340 4 spd.

I had my stock radiator recored with a 3 row 5/8" tube core, stock fan shroud and Hayden short shaft fan clutch. Ran the car around this weekend and never went over 185 (180 thermostat) sitting in traffic and temps were in the 80's. Motor is a 410 stroker making a little over 510hp at the crank.
