Proper cooling for 74 cuda w/ a 440??

[rebelcuda73]

Trying to finish my 74 cuda with a 68 440 4 speed project. A friend had given me a griffin 1-2622x  26x19 radiator. Its there pro series though it does not have mounts. I had thought about trying to mount it some how though also though about selling it and installing a direct fit radiator. I know that griffin also makes a direct fit which costs 274.00 but also seen two champion radiators one 3 core 26x19 190.00 and a 4 core 26x19 280.00 both are aluminum radiators. The car will have some where around 450 hp and will be used for the street just not sure which way is the best to go. Even thought of finding someone in Orlando FL that welds aluminum to weld brackets on the griffin not sure of cost though. I remember that the old original 4 core radiators were good though could still over heat when stuck in traffic. Looking for the best way to cool the car!!!

A lot comes into play , most alum rads should keep it cool , you need to have a good water pump , thermostat & a big clutch fan with shroud will work the best . No way I would rigid mount an alum rad , it will crack for sure , look at every new car they are all isolated in rubber mounts . I would devise some pin & grommet or shoe system to mount it in .

If you enjoy driving your car and live in areas where summer temps often hit 90+ degrees, you'll invariably end up stuck in traffic somewhere where even the best radiator may be insufficient to keep that big block cool. I'm speaking from experience and almost overheated leaving Carlisle and getting stuck on the DC beltway in mid July.

What I would recommend, that in addition to whatever radiator you choose (and I have a 4-core aluminum that does great) that you install a back-up electric fan either controlled by a thermostat or switch. I installed an electric fan I have wired to a fused lighted switch. If I get stuck in traffic, it's 98 degrees and we're going nowhere, I simply cut on the electric fan (I think it's a 16" fan) and it keeps me cool even when just sitting. It's just a thought, but I'm telling you, it's a life saver!! Good luck with the radiator/cooling project!
