Im thinking about putting a 440 or maybe evan a 465 big bore kit on my 400ex I just wanted to know if they have any problems with over heating, does any body know?

well they do run pretty warm. i dont have on but a close buddy does. we got a larger oil cooler and bigger oil tank and he does alright now. i dont know if the temps were somethign to worry about before we did the cooling stuff, but it made us nervous so we did it.

how much does that cost?
