I am running an AFCO alum. radiator ($179) in 67 Camaro with 383. The temps are around 175-180F, 160* t-stat with a clutch mech. fan and a shroud. Temperatures with my stock copper radiator were in 195-210F range. Big difference.

Are you using a fan shroud?

Yes i have a shroud but the air flow is restricted a bit since its a transam, all the front bumper are closed.. And to add to this, i have the intercooler under the front bumper that cover most of the hole where the air came..

on the road i run at 210 but they go higher when i drag or punish the engine abit..

I guess i would have to make hole in my front bumper to help a bit...

Is the factory under bumper air dam still in place? Or is it all mangled from curbs? If it's not there, or all smashed up, you will need to replace it. Due to the very small grill opening, the airflow must be diverted from under the car, and if the dam is gone, you won't have sufficent airflow to cool the radiator. I ran into a similar problem with my Z28, especially if I was working it.

Is that the scoop for the intercooler? It looks like it is sitting right about where the dam used to be. It looks as if it might be possible to deflect the waste air coming out of the intercooler to the "stock" airflow path into the rad. It may not help too much, due to the heating of the air by the 'cooler. If no more airflow is availiable, going to more cores may help, also may not. Other that tnat, it looks like some fiberglassing and custom bumper designing are in the near future.... . I kinda hope not, that car looks like it has a fairly fresh coat on.

This installation ain´t pretty but it got my coolers into a well vented area.
The airdam is essential, it causes a vacuum in the engine compartment which draws air through the radiator.
I am going to widen mine and add at least an inch to it´s depth.

In the first attachment the trans cooler is on the right, oil cooler on the left.
In the second I had them one behind the other halving the space for air to enter.

This is what i think right now.... I guess the only way i can have more air is by doing some modification on the front bumper but thats not an easy task to do btw...
I have no other way to mount the intercooler & for sure the intercooler block the air path where he are its almost the only place the rad will get free flow..
The front of this car is very tight & close..

Perhaps a sollution......

Could you make some 3-4" holes in those aluminum plates on the left and right side? If so, you could fabricate a sort of scoop that would pull air into that plate area. On the back side you could run flexible hose to the front of the radiator. Not too pretty, but better than cutting up your bumper.

on each side of the intercooler (left & right) ? Its just plastic, but i have the intercooler piping that goes under this (3" tube).. May be i can check if i can find a way to route some air by there but not sure i have room to do that.. I will look into this to make sure. thanks

Just a suggestion. I dont see any other way to increase airflow to the radiator. Even the ducting will not help much at slow speed or while parked. Driving down the highway it could help some.
