somethings not right here

I don't know if the radiator is up to it either. It is a Champion MC526 radiator. Mfg. says it will cool up to 450 HP. They didn't say that cool meant to be in traffic though. It does fine unless I run it and then idle for a period of time. It is the biggest radiator I can put in it because of the core support. It is the same size I had in it for 17 years before I stuck this in earlier this year. Now if I wanted to cut out the core support wider and do away with the overflow bottle I could probably go to a 26" radiator but I am not even sure that would cool it down so I am thinking when this 16" pusher goes in this week, it will tell the tale.

A 26" rad would almost certainly help, cooling a big block w/a 22 incher is a big ask. It was previously suggested you should try to find a shroud that will fit, the existing one isn't helping you at all. If you're already wired for a pusher fan, whats keeping you from ditching the factory clutch fan and going electric?
I didn't have much space between water pump snout and rad., so I got a dual 11" puller the clear the w/p, it fits the 22" Champion like it was made for it.
