Can the OEM radiator be replaced with an aftermarket aluminum radiator?

Re: Radiator
 

Yes. Stock dimensions and appearance.

Re: Radiator
 

Yes. As long as it isn't too small within reason

Re: Radiator
 

So I understand this correctly, you can replace your OEM radiator with an aftermarket aluminum one in Stock? ( size being the same).

The best thing to do is look in the rule book to see what the printed rule is. After that if you have a question call your division tech director and ask for a clarification of the rule. Then there is no question when you get to the race if your car is legal

Re: Radiator

Thanks

Re: Radiator
 

I will ask our divisional tech first before ordering. Thanks everyone.

Aluminum in the El Camino with zero questions thus far. Painted black one probably could not tell from factory.

Why dose the Be-cool radiator cost more than the champion radiator are they that much better ? Which radiator did some of try and why ?

Re: Radiator
 

I went with the champion for my build... super nice radiator and they were great to work with, I had them replace the ends with AN fittings. They also have a nice shroud.

Ken,

I ended up going with an aluminum radiator from DeWitts for my 71 Nova. I ordered it painted black. They make a nice product and it fit well with my factory hardware.

According to NHRA Rulebook, Stock classes:

"Full size radiator mandatory for body used. Aluminum radiators permitted; must retain stock dimensions and appearance. Cutting, denting or elimination of any body, fender, radiator or grille panels prohibited."

Basically, this means that a top/bottom tank (vertical flow) radiator cannot be replaced with a cross-flow radiator and the hose inlet/outlet located must be in the original configuration. Most cars were available with heavy duty radiators, which typically had additional rows of tubes, therefore I don't think that there is any restriction on the thickness of the radiator core used.

Re: Radiator
 

Main thing it's not a round track or street car so you dont need the 3or 4 row core , so a 2 row should work wright . The cost is very different between different makes so is it a quality thing or paying for the name ?

Re: Radiator
 

Ken, check out Spectra Radiator. I used one on my car, direct factory aluminum replacement and very reasonable, and good fit. I believe any NAPA can get them. Also, keep in mind most aluminum radiators I have seen have 1 inch cores vs 3/4 inch cores like most factory radiators.
