Radiator distance from core support

Can someone please tell me how far off of the core support a stock radiator sits from the core support?
Aside from fan clearance, how will the fan shroud mounting be affected if the distance from the core support is farther than stock. I just received my radiator and it sits about an inch or more from the core support and I'm not sure if that's correct or not. The radiator is a direct fit.
Thanks, Jim

Re: Radiator distance from core support

I believe the tank seams on the side of the opening are about 1/4 inch?

The OE shroud bolts on top via bracket and clamps onto two tabs on the tanks sides.

Re: Radiator distance from core support

Big gaps can negatively affect cooling performance. Fill it with foam if you find the car runs hot.

That's what I figured and can't understand why a direct fit radiator would be that far away from the core support. I seem to have bad luck with radiators.

Re: Radiator distance from core support

Jim - Traditionally the radiator core(s) is(are) centered front to back between the tanks. As stated the shroud bolts on the top and clips on to the tanks. I would expect yours are but have seen some weird configurations of non OEM style rads over the years. Are your cores centered on the tanks?

If so the real question is how far are the tanks off the front of the radiator support? If they mount up like the factory radiators, then the factory shroud should mount on top and clip on to the tanks with no clearance issues.

I went ahead and bought from one of the sponsors. The radiator core is centered to the tanks and that looks fine. There were other issues of damage possibly in shipping or packaging but that's another topic. The radiator sits off of the core support close to an inch maybe a bit less. It was late when I was trying to mount it and one of the brackets was bent so I couldn't get all four bolts in so I was dealing with that and didn't measure but I'd estimate looking down from the top it sits an inch away from the core support.
It looks much too far away in my opinion but I'm not sure. I quickly measured the entire width from the back of the bracket to the front of the tank and it was about 4 1/4". The ad says the width of the radiator is 2.7" so let's say 2 3/4" so the bracket extension if roughly 1 1/2". the side lips on the core support are roughly 5/8" so I'd say I've got about 7/8" of space.
Hope you understand my rambling.
Thanks, Jim

Re: Radiator distance from core support

When I dig out the driveway in the morning when I get to the garage door I'll take a tape measure of of the distance on mine for you.

Re: Radiator distance from core support

Be sure to use two wellnuts to mount one side of the radiator.

If you are looking for originality, this is as close as you can get.

It's not originality I'm after, just fan clearance and if I plan to use a fan shroud, I want the brackets to fit.

You should definitely run a shroud unless you want overheating issues.

There is some space between the radiator core and the core support as you can see in Rogers pictures and as mentioned by Brian with the core centered between the tanks.

I'll take your advice and order a fan shroud.
What I see from Rogers pic is a lot smaller gap between the core support and radiator but it is hard to tell without an actual measurement.
Thanks, Jim

Re: Radiator distance from core support

I would not concern myself with the space between the core and the core support.

How close are the tanks to the support when the radiator is installed?

What are you using for a fan? Clutch? Fixed blade? Flex?

When installed how far is the fan from the radiator?

That's what I'm attempting to describe, the distance of the tanks away from the lip that extends outward from the core support. I'd say there is close to an inch of space.
I'm using an 18" derale rigid race fan. I have a 2" fan spacer from my previous set up that was never an issue with radiator clearance. I have plenty of room between the belts and fan... roughly 3" so I can use a different spacer.
With the spacer I have, the fan will not fit. If I had to guess, the fan and radiator overlap about 3'8".
I feel if the tanks were about 1'4" off of the core support which another poster responded that his original radiator was spaced, that everything would go together perfectly.
Hopefully I'm describing this so you understand.
Thanks, Jim
