I have a 289 bored over, I over heat when I’m idling or drive it a while, it’s the normal fan not clutch, with champion radiator I’ll loook at the second linkA couple of questions... are you currently overheating and/or do you even need a fan shroud? I've honestly never run one before and have never had any cooling problems, of which I also even have a Champion brand aluminum radiator. Also, what particular application are you running? I'm assuming it's for a 1965/66 car? Is it a v8 or 6 cylinder? Electric or clutch fan? If you're looking for an electric fan for a 1965/66 car with a 6 cylinder then you want a 251FS16 that's the first link below.

The fan is about an inch off the radiator fins it had an extended bracket to get that close but still over heats, I flushed the system, put some wetter wet. And I’ve said that it’s worked but could it be it has a bigger cam and bored over?How far away is your fan from the radiator?
The factory style shroud has stand off brackets that the shroud bolts to.
There are different brackets for different thickness radiators.
The mechanical fan and shroud is the easiest solution and should work just fine. It worked for millions of Mustangs for over 50 years.
“….. but could it be it has a bigger cam and bored over?
It’s 30 over, I have a a mechanical gauge that that sits on 180 degree but when it gets to red is about 270-290 until I start driving and goes back to about 200.how much bored over ? Usually +0.030 is no problem , more than that could be an issue.
do you have a mechanical temperature gauge installed ? It would be helpful to put a number to your overheating issue. Up to 230 F for brief periods of time is no problem, especially if it comes down to the mid 220’s F when the car is in motion.

I have to comment that I do not have confidence in a gauge displaying a temp of 270-290 F. That’s way to high to be accurate (or believable). Not saying you don’t have an issue, but the gauge is not reporting correctly. If you had temperatures that high the motor would likely be seizing.It’s 30 over, I have a a mechanical gauge that that sits on 180 degree but when it gets to red is about 270-290 until I start driving and goes back to about 200.
That’s what I’m looking for thanks a lot!The above link is what will work for an electric fan. If you have a belt driven fan, try looking at one of the products in the link below.
