I have a 406 that wants to run hot. Was to ld I could put bypass hoses on it but they are all for predrilled heads. My intake has water connections in the rear but what size hoses do I put on it and to where

 

Check your radiator for flow. Even though my "new" radiator was 3 years old, I too ran hot. I changed from a 3 core brass to a 2 core aluminum and the temps are now under control.

 

Brand new griffin alum. rad. Flow is good just cant keep up.

 

Not sure if I'm understanding you exactly, but I think I get it. From what I've seen, most people run lines from the rear water crossovers straight up to the front crossovers. Not sure on the AN sizes you'd need.


Sorry if this wasnt much help
