410 Stroker rad

After surgery set me back, and some really bad weather, I'm finally ready to turn the key for the first time.
This motor supposedly dyno'd 500HP and 516 Tq, so I'm thinking my stock 340 rad may not be enough to keep it cool(if it runs).

Wondered if anybody had a suggestion for a radiator that will allow me to use my shroud and fan. So many aftermarket ones out there and they all say "direct bolt in".

Like to hear some useful advice, if needed.

THANKS!
