1970-1972 LS-5 Fan Shroud

[D S.]

What are the original part numbers of both the LS-5 fan shrouds with and without AC for 1970-1972? 3956119 with AC and 3956109 without AC? Or are they the same part number but has to have an extension with AC?

Thanks,
Scott

GM #3956109 is the 69-72 small block fan shroud. GM #3956119 is the big block fan shroud. However, my recollection is that a different shroud was originally used for big block with C-60 applications. I do not recall the part number. I did research this point some time ago, though, and that part number should be someplace in the archived posts. I can't look up the part number right now since I'm 3,000 miles from my references, and I just don't have every part number committed to memory-----some but NOT all.

Both the 3956119 and the other big block shroud have provisions for an attached extension. Also, as I recall, the 3956119 may have replaced the other shroud for SERVICE and I think the other was discontinued a VERY long time ago. The 3956119 was discontinued several years ago.

Thanks, Joe, where ever you are.

You can be sure that Joe is in VERY close proximity to outstanding lobster and clams .

Scott,
As I recall from prior research I did, the 1970 BB C60 shroud was a one-year only.
I have written down a part no. 3974015 with 3956089 for the extension.
These are really hard if not impossible to find...in my experience.
If you run across a couple of 015 shrouds, let me know 'cause i need one.
I don't believe they are in reproduction either.

VERY, VERY close. In fact, I have 5 pounds of steamer clams and 2 lobsters just a few feet from me right now. I had 3 giant lobster rolls for lunch (about the meat from 1-1/2, 1-1/4 pound lobsters per lobster roll). Last evening I had fried clams and fried oysters for dinner after having 4 giant lobster rolls for lunch. Heading up to New Hampshire tomorrow and I've got 6 giant lobster rolls "for the road".

I'll have a complete report on my lobster and clam eating totals after I get home.

GM #3974015 was the part number for the big block with C-60 fan shroud. However, it was used for 1970-72 big block with C-60 and not just 1970. It was discontinued in December, 1973 and replaced by GM #331869. That shroud was pretty much "still-born" and replaced by GM #339175 which was the SERVICE shroud for 1973-75.

I don't know which to address first....the seafood or the fan shroud. I guess I did the obvious. Even thought it's just after 7:00 AM here in Texas that seafood you described sounds delicious. The closest I can get to seafood around here is Dead Lobster.

Thanks for the detailed part numbers and the information on the fan shrouds. On this TDB one gets a lot more bang for their buck.

Scott.... you already have the most reliable information possible regarding the correct part numbers from Joe...... but to add just a small bit of additional info,,,,, the small block with C60 shroud (4spd & almost sure in included the LT1) is the fiberglass shroud that doesn't require the extension. However, I believe there is a small additional piece near the bottom that completes the shroud's enclosure. This is sometimes referred to as an extension... but really just completes the circular enclosure.....hope this helps a little more....

Better not have your cholersterol checked right now. You would probably have a heart attack if you saw the numbers
