Default 400ex cooling

I am having a big bore 440 installed on my 400ex and i know there might be some issues with cooling, I know there are some things you can buy such as air shrouds and an aftermarket oil tank, does anyone happen to know if anyone makes a larger oil cooler for a 400ex.

P.S. I bought the Air Shrouds for my soon to be 440ex

Thanks Bill

Pingry makes one, I know there is others also. Some guys run 440, without coolers. I have a 440 stroker, that has 3 years on it. It has only been too hot once. That was on a race track with 3 re-starts. If you are jetted right it should be OK.

the larger oil tanks will not do much for the temperature. a larger oil cooler like the mickey dunlap fst cooler will help cool the oil though.
