So what depicted getting a shroud then ? 6BBL and Shaker w/ 440 w/ A/T ?
I would go out on a limb and *theorize* that if a car had a 440 with a 22" radiator that it came with a shroud to maximize the cooling with the smaller radiator.
Tossing a shroud on had to be cheaper than a 26" rad, I know "back in the day" my 22" radiator was marginal with the miles that were on it.
A Chrysler engineer I'm friends with stated that a radiator loses something like 50% of its ability to shed heat in the first 4-5 years.
P.S. My GTX had the same fixed fan as the 440+6 car shown above, what a noisemaker that was.
