Anyone know if they are similar. Or is the MarkVIII fan better. I have a derale dual fan that is supposed to flow 4400 cfm, but when I am in stop and go traffic it gets pretty hot and was thinking of changing to one of these.
I never heard of anyone using an 03 Cobra fan, but if it can cool 390 HP 4.6 then it should work on a 347. You cant go wrong with the Mark VIII fan, I have one, it moves A LOT of air; and I never heard of any cooling problems with those fans.
