    Hi Guys, I have a extra radiator for my 46 ford that has been re-cored, but never used. My question is, if I have the radiator shop block off 2 of the outlets and change the filler neck, will it cool a pretty much stock rebuilt 283 with mild cam? Or would it be better to by a new Walker radiator. Thanks.
     
  2. Yes it should cool it just fine. I have had 40s cars with stock radiators and small blocks and they cooled just fine. I'm not sure what style of fan you have but you can always put a big fan on a sbc, or an electric fan. Also if it's not a pressurized system you can have the shop set it up for pressurized and that will give you a higher boiling point.

    My 46 Ford convertible with several SBC's in it has had a Walker radiator in it for 20 years. Walkers are pricey but worth it. Who else gives you a ten year warranty?

  5. There are 3 major considerations for any radiator; air flow, air flow, and most importantly, air flow. Take care of those and you should be fine.

    I have a 327 in my sedan with the stock 6 cylinder radiator. I put a 10 pound radiator cap on it, and extra pressure caused the upper tank to crack. I now use a stock 6 pound cap and it seems ok. The motor runs about 180 degrees, with an electric puller fan.
    I saw a cool two into one manifold made once for the upper outlets of a stock radiator. It was sort of u shaped with a single outlet hooking up to the Chevy engine. It looked good, and was creative.

  7. stock ford V-8 Radiators have more capacity than you actually need...AND they were used many years BEFORE there was such thing as "Walker"

    My old '39 has a worn out 283 with the stock radiator. Previous owner used round wooden blocks and hose clamps to block one side, and it worked fine for years. Running the stock cap, and if anything, that combo ran almost too cool. You should be fine.

    If they'll cool a flathead, they'll pretty much cool a nuclear reactor. Haha

    I learned a long time ago that when it comes to brakes, cooling and steering you buy the best.

    Thanks, that 2 upper hose idea sounds like a good period correct idea, I am a seasoned fabricator, and just might do that!
