67 Impala SS Convertible Fan Shroud

Did the 67 Impala with a 327 come with a fan shroud if it was not equipped with air conditioning?

Yes it did. All the 60's chevy's had fan shrouds otherwise they get really hot while idling or in stop and go traffic.

Strangely, not all '65 and '66 Impala cars had Fan Shrouds. Not real sure where they drew the line at, but Small Blocks w/o Air did not have them anyway.

My 1966 Impala SS with 283 and power glide had a fan shroud and it didn't have AC. My brothers 66 Impala with a I6 and three on the tree had a fan shroud, granted of course it didn't stay a I6 car very long.

Are you referring to a Fan Shroud or a Radiator Spacer? The '65 and '66 has a Radiator Spacer that goes between the Radiator and the Radiator Support, but technically it's not really a Fan Shroud, although some cars did actually have a Shroud.

Nope, I distinctly remember a shroud between engine and radiator that the fan stuck half way into. I do also remember trying to find one in a salvage yard was next to impossible. The spacers you are talking about were for the Iron duke engines, at least that is where I saw one on a 63 Impala. The little I4 wasn't long enough so they had to space the radiator back to the engine. Too bad those I4's only saw their way into fleet vehicles. They were tough little engines.

I'm not big into restoration so i don't know the definitive answer to this question. I can say a fan shroud will always improve the ability of the fan to move air at low speed.

From my meomory the base 283 and any six or four cylinder engine didn't have a fan shroud. All A/C and high horse cars had it. The problem with this definition is the 327 stradles the line with the base being rated at 275/300 horsepowr (same engine numbers changed or marketing reasons), and the 350 and 360/370 horse variants (the 360/370 was the same engine but the 370 only appeared in the Corvette so it's higher horsepower rating was again for marketing reasons.

Most likely because most '65 and '66's did not have one.

Maybe so, but '65 and '66 V-8's had the Spacers that I was talking about and there were 2 sizes, a 4 Inch and a 1 3/4 Inch. Basically speaking, the Big Block got the Narrow and the Small Block got the Wide.

Here is a line from one of the experts on Chevytalk:

--"The big block spacer (thin) is for the wider radiator (4 core). If you have a small block with A/C, you also have the thin spacer and the larger radiator.

The small block radiator takes the 4" spacer, and only without air conditioning. It also has no fan shroud, just a finger guard on the radiator."--

Notice he states No Fan Shroud.

Here it is here 2nd post down:

To add a little extra, I have had 13 '65 and '66 Cars here and I still have 11 of them. None of the '6's and Small Block have "Shrouds".

Not counting the 100 others of the hoods I've been under.

I also maintained the city of Tampa water departments fleet of radio delete three in the tree four cylinder 1966 Biscayne two doors (14 of them) and in line six light trucks (another six). None of them had a shroud.

My mother's 283 four barrel powered 1965 Impala did have a shroud (but I never considered it high horse). being from Florida it also had factory air. (none of the biscaynes or C10 trucks had air with the city as they wanted their employees out of the vehicle working not enjoying time out of the sun and humidity in an air conditioned vehicle. My mother's 1968 Caprice had a 350 horse 327 and factory air so it had a four core radiator, motor oil cooler, power steering pump cooler, and an external automatic tranny oil cooler with a shroud.

But doing oil changes and maintenance work on customers cars I have seen a lot of B-body cars with and without shrouds. It may be it was a factor of were the cars were assembled as to whether a shroud was installed with cars built from the south were it is a lot warmer getting them and Yankee built cars from the North not so much. GM used to have a lot more assembly plants spread across the USA back in the sixties, compared to now where they have none.

I can remember when my father took his 68 Caprice to either get it inspected or for a wheel alignment and watching as a kid the mechanic rev the engine for some reason and the motor jumped up and the fan took out a huge Chunk from the shroud!! I wonder if a lot of those missing fan shrouds were from pre recall defective motor mounts?

Right, from about '66 on Fan Shrouds became Plastic and are known to crack or worse. Originals are pretty hard to find. The Steel '64 and earlier ones are much more common.
