Still Too Hot

I have very similar set up as you in a 67 cuda. I have the 3 row champion radiator with the shroud and two 10" fans. I would heat up as well to about 205 then it would level out. I am running a 180 thermastat confirmed by heat gun on kitchen stove. Solution. I installed to 10" fans on the front side as pushers. I wired those fans to a manual switch. The puller fans I have wired to a sensor and a override switch. I also have a 8 blade water pump as well. Horse power makes heat. So a total of four fans. Two pullers two pushers. With this combo I can run 185 all day long.
