That is a half system , I am looking for a full system to include exhaust manifolds.

S,
Thanks, I'm pretty anal about my equipment... Hours are ~290, 90% saltwater use....

I used monitor and am very happy with the product. Stock 502 mpi mag almost all salt water usage. No overheating issues

if you do go closed cooling it would be smart to run only distilled water in your cooling system about the first 5 times out and drain and refill ..The distilled water will help pull the salt out that has leached into the cooling passages. If you just add a coolant you risk turning it into a gel...

Plenty systems around for Factory power , what this hunt is about is finding a FWC system big enough for more cubic inch/ horsepower and also cooling aftermarket exhaust. That system a few post back is awesome but isn’t a full system.

More likely it would seem to be for larger cu. in. engines a custom fabrication of sorts would be required for a FWC systems & exhaust........I can see this getting very expensive.

Park35, what is the size of that exchanger 5x30?

5by 27...hi flow

Open 72.......So we both have tall decks (mine BBC 572 cu. in.) wondering what size heat exchanger would be adequate to cool a full system.

Same here, and I'm either going to put KE manifolds or IMCO Powerflow Plus on my 572....https://cimg1.ibsrv.net/gimg/www.off...4806e6d13e.jpg
