So just people know that part # above from Flex is reverse rotation the 5655 is the one for normal rotation for the older stuff.............but they are discounting them for what ever reason. So I got this one HDA-2797 instead......that I'm trying out. Put it on the five blade and it wasn't still what I was after. So there was a guy selling some seven blade 19" fans here, for someone else that I bought. I'm going to post some pictures of them. I'm interested in which one you guys think will be better as far as flow.

if you happen to not have room for a clutch fan....which is looks like you're very cramped for space...i know a guy using the flex a lite 7 blade flex fan on his 632 cube BBC(street car). He likes it plenty. the uneven spaced fan blades keeps it quieter than the typical flex. That might give you a little more cooling than what you have in there now. If there is room for a clutch fan setup, I always prefer it as a first choice. here is that fan. it comes in 17 inch also http://www.summitracing.com/parts/FLX-1817/

Ok, update. Those fans weren't mopar once I got them in the mail. Yes, I could put them on, but doug deeper in the mopar part numbers and got this fan instead which I show the part number and what it looks like later.
Lets step back and tell you about the sever duty thermal clutch that I bought on the 20" AC five blade fan which factory to the RC. It would cycle about 12 to 14 degrees. Say it would get around 202 then would drop the temp around 188. One would ask what's wrong with that? Nothing, I guess, I'm still learning about the nature of the clutch fan. Like I said early in this post I've always taking them off in the past run straight style fans or flex fans.
Her is a pictures of the five blade fan with the that thermal clutch that was on this RC with the 360. In this picture it's on 440.

This fan is awesome, yes it's a little louder.........hardly noticeable, but more so that the five blade. This fan is the same diameter 20" seven blades, but has 2.75 pitch or depth compared to the five blade of 2.25(which those two other 7 blade fans were 2.25 pitch like the five blade) This thing cycles from 208(which it varies) sitting in my garage after coming back from a drive and once engaged it will drop to 183 right above the thermostat every time.

third, don't mind the coffee mug in the last picture......it looks funny doesn't Almost forgot the part number for this is: 3462186 Which by the way the HDA-2797 according to Hayden's site it will need at least a fan with 2.5 of pitch to work right.
