Indy heads single water crossover /single plane manifold.

That's just ridiculous when people say that electric fans don't work.....the simple truth is that power is heat and the more you have the better the cooling system you need.......if I can have zero issues with a 571hp 415" and then same zero issues with a 976hp 434" with the same 2 core 1.25" tube Wizard radiator and a 16" Spal fan and others do have issues it's not the electric fan theory fault......you have a problem with your car period!!!!
