fan shroud ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i just installed a champion radiator and still have a belt driven fan. i dont

have a fan shroud and was wondering if that would be a big issue with

cooling. i did a test drive and held between 180 and 200.

anyone running with no shroud and no issue with overheating?

is there a bolt on shroud that i can swap in? thanks

If it turns out you need one they sell them at Brothers and ecklers.....

I have a 400 smallblock with an aluminum radiator in my shortbed. No shroud and it never ran hot with a belt driven fan. In the same range as you describe.

My truck has never had a shroud and it came from Arizona.

Live in Texas, stayed around 105-115 all summer and mine never got over 200 without a shroud.

Just wondering....... My truck didn't come with a fan shroud, but I'm wondering if an original would fit my 64 truck? It has a later 350 Chevy small block. The radiator appears to fit as original, but would the fan on a 350 engine be centered in the same spot as the original 283?
Haven't had the chance to see what it's going to do in warm temps, as I just recently got it on the road after restoration...... highs are now in the 30's.
Thanks.

ALL smallblocks are the same size physically. The only difference would be if the engine location was moved front/rear or if you have a short or long waterpump; or a combination of these options with original engine perches. I would guess an original shroud would work as long as the gap between the engine and radiator were relatively the same.
