I did notice some gaps on the side of the shroud. I may try to seal those. And seal the gaps between the radiator and radiator support so all air must travel through the radiator.

Anybody have pictures of their stock fans?
It is a factory fan with factory numbers stamped on it. Currently i have the numbers facing the radiator....
Still hoping for pics of someones stock fan. I want to see what side the part numbers are on
I don't know which side the parts numbers are on, I just look at the shape of the blade. And the smooth side of the rivets, face forward. 1st pic is my fat block, 2nd is my 406 SB.
Son of a bit**..... in your pics the part number faces the back....
This means this fan and my last fan (not installed by me) are backwards... lol
If this is the problem ill be thrilled and pissed at the same time

Lucky flipping a fan is a 5 min job.
Still sucks...
i highly doubt that is/ was the issue but every little bit helps

I’ll bet it makes a notable difference.
yeah, if your fan was backwards, it'll be a HUGE difference.
Also, all of your internet friends will make jokes. :P

Doing some reading on hotrod forums and it turns out I am not the only person who has done this. I guess it should say front on one side but since the guy i purchased the fan from painted over it i have no reference.
From what i read the part number stamped on the blades face the firewall.. mine was facing the radiator. I suppose if the pictures and info i found are true my fan was indeed on backwards.
I put it on to match the fan that was already on there when i upgraded to the 6.2 fan. I guess this means whoever installed the last fan also had it on backwards.
Maybe this is contributing to the overheating issue i have been having since a little while after the machine shop built the engine. its possible that without the AC condenser the backwards fan was able to keep up but adding the condenser pushed it over its limits.
I still need to drive it but it seems to pull the same amount of air as it did before so i don't know that its really the issue.
we can all laugh about it though, either way i installed a fan backwards and that is funny
IF and its a big fat IF this has a major impact this thing should run soooo cool, my entire cooling system has been rebuilt and upgraded.
one reason im skeptical that this is the "big issue" is my crappy luck with the windstar fans and how adding that 2199 cfm pusher only helped a tiny bit.

I had a neighbor put together a pretty impressive 408 small block for his 88 k1500. Spared no expensive and put on a edelbrock Victor Jr high flow water pump along with lots other go fast goodies. He did however use the stock serp drive from the 305 he pulled out. Care to guess what happened next?
He was breaking in the cam and came to get me to ask why the engine temp was starting to go high. Took one look and saw the fancy aluminum pump and asked if it was reverse rotation or not. I got the deer in the headlights look. I explained the difference and showed him which way the pump spun on my Nova with a v belt and compared to his.
Needless to say he swapped the pump off of the 305 and it cooled down just fine.
I am about to that point with this one.
I actually kinda kick myself for not getting the cowl hood like i was thinking. i bet it would have helped with cooling
Oh, one other thought. Your Windstar fans were probably less effective with the mechanical fan trying to push instead of pull. Kind of cancelling each other out.
Seems like flipping the fan should help pull more at idle. Also, are you sure the clutch is for a V-belt fan? Maybe not a serpentine set up? They make heavier duty clutches too. Might spin it faster at idle?
I ran the windstars as pullers in place of the mechanical fan.
now im running a pusher in front
I have a hayden severe duty for a 1978 BBC so i hope its the right one and its the most heavy duty one i could find
Cowl hoods aren't meant for cooling...
The proper name is Cowl Induction, as they are meant to be a fresh air source for the carburetor. Put a tray under the air cleaner that seals to the hood when it is shut. Air comes in through the cowl, taking advantage of some sort of aero driven vortex magical wizardry that happens at the back of the hood at speed.
Not saying a cowl induction hood that wasn't proper set up for induction, but just kinda there, couldn't help with cooling, but I don't know that it would be right hood for releasing heat.

That's what he's saying. You're mechanical is trying to push air forward out the front of the radiator while the pusher fan is pushing the air back into the radiator. Making it a stalemate.
