Radiator Placement

Thin fans, like the Spal "medium air flow" fans, 11 inches in diameter, mounted low enough on the radiator to miss the headlight bar (not centered) should allow the radiator to stand upright in the oem position. The Spal "high air flow fans" are too thick, they'll hit the forward bulkhead. To use the Spal fans you would have to fabricate a fan shroud, or install them without a shroud on metal straps. Remember the fans need to be spaced about 1/2 inch to 1 inch away from the core.

I haven't actually done this myself (I decided to keep the fans in the OEM position), but I did size things up, I spent a lot of time looking at the options a person may have. I had both sets of Spal fans on hand, but I didn't have the Flex-a-lite kit people generally use with the Fluidyne rad. But since the Flex-a-lite kit centers the fans on the fan shroud, I doubt that the radiator could stand upright with the Flex-a-lite kit (the fans will hit the head light bar).

It will clear on the '72 and later. The '71 needs a little massaging of the fan shroud due to the center support bracket for the headlight bar.

I currently have a Fludyne with the Flex a lite system (2 fans and shroud) in #4008. Tight fit but is in and works fine

Didn't realise you had to do any mods to lay the radiator down.
I have a fluidyne rad with spal sucker fans. I did make a SS shroud for it but to lay it down was two straps that i got from Bob Byers with the radiator so bolted them to the rad, and the other end to the original holes job done, you may require a bit longer radiator hose. you just won't be able to run the original fans in place.
I have left the original fan mounts in the car in case at a later date someone wishes to restore to original.

Hey John think its just his radiator lay down kit http://precisionproformance.com/coolingsystem.php

The straps for the laydown kit are just a piece of 3/32 steel with a hole at each end. You can make them easily. I installed the fans to the shrowd and the shrowd to the radiator. I installed the radiator in the car and measured how long the straps needed to be. Simple.

Here's a little more info, I went with a pusher and sucker setup:

The radiator laydown kit is not just a pair of straps. There is also a pair of lower brackets to relocate the mounts for the locating pins on the radiator. I ended up removing the laydown kit on my car.
