Very interested in the 2947 clutch plus the 5 blade fan. After installing my 400+ HP 360 (just guessing) I had cooling issues. Installed a Griffin aluminum rad and the issues vanished. After putting the cuda on the back burner for sometime now I've started back tinkering with it again. Never got around to fully completing the fan and shroud combo. Right now my fan is a steel non flex 6 blade with no clutch. At one point I had a vicious fan package but I couldn't mount it because the clutch was really close to rad. Sent it back for refund.
After seeing a fan shootout video that compared how different type fans rob horsepower it showed my current set up robs a shade over 30 horsepower. Yep... 30 horsepower. To me that's a ton of HP because of the fan. A standard clutch type robbed something like 14 HP.
EDIT: Never mind on the video... ya'll have already seen it.... lol
