I ran 2 4 in ducts as you described when I first bought the MH and had the leaking exhaust gaskets replaced what I found was that the following year the exhaust manifolds were cracked between the ports(not leaking)from rain water getting in hitting the hot manifolds. My scoops were lower under the grill so be careful. Headers and other mods helped remove a lot of the heat from the dog house and added way more power.

Gjac,

I may be mistaken but I think the 454s had a problem with the exhaust manifolds cracking between the exhaust ports and most guys ended up with headers. The water mist probably didn't have anything to do with it. I'm sure somebody else will chime in on this.

For anybody that's thinking about a thermostatic switch to run a pump or aux fan etc. I wanted to give an opinion. I recently converted a car to electric fans with a thermostatic control. After 2 Hayden controllers failing in a 6 month period I switched to a Flex A Lite control and so far so good, but, it's only been a month or so now. The Flex A Lite switch seems a little heavier and is rated to run a fan without a relay, although I used it to operate the relay I already had in place. A failed switch on a mister system isn't as crucial as a main fan, but, still a pita! I just wanted to pass on my recent experience with Hayden products. I bought the Flex A Lite control over the counter at NAPA.

FWIW, Hayden tech support suggested I buy another one of their controllers..........naw!
