69 barracuda electric fan selection

Hello folks

Excuseme my bad english, i need your advice

Recently we repair my 318 engine.

I put 265 dual energy comp cam, flat top pistons, stock magnum heads with hughes springs, msd 6T, edelbrock 600 cfm carb and hooker headers.

I remove the stock 69 radiator and replaced with a 3 row 26" core radiator. Its wider than the stock one, but also its thinnest, so the distance between fan and this new radiator core its bigger (no shroud)..

At stop lights, the car is getting hot quickly, i am thinking on use a dual electric fans with a shroud to avoid that heating (this car is for weekend driven only)

What electrics fan would you recommend me? how many cfm?
I saw on ebay a shroud with two electrics fans (1400 cfm each) for about 169 dollars. this is the link
