Diaper question
 

When you have a class race and you want to cool the motor how do you drain the block if you have a diaper?

I've seen a bypass installed in the radiator hose that allows you to quick connect an external cooler to add to the system. Something like routing the radiator flow through a Coleman cooler full of ice water.
