Hello

I wonder if this numbers from the motor and windshield can tell me something about the car? My car is a Cutlass 1971 Ive been told it is a 350 V8 engine but thats about what i know.

Between the hood and the windshield is a plate with the following numbers
Body by fisher
ST 71 33687 G 62528 BDY
TR 937 75 A R?? (cant see what those 2 last letters are)
05A

On the panel inside the car
3368716123786

On the engineblock in the front
557752-3B

On the engineblock on the firewall side
CFD 75 And some watch symbol i think. And that symbol points "ten a clock"

Does this tell you something?

Very happy if someone comes up with some good information

Thanks!

 

VIN 3368716123786

• 3 — Oldsmobile
• 35 — Cutlass V8
• 87 — Holiday (hardtop) coupe
• 1 — 1971
• 6 — impossible character - must be a letter, not a number. Probably a "G" for the Framingham, Mass. assembly plant
• 123786 — Sequential production number

Engine 557752-3B
1977-1980 350 with windowed main bearing webs - about 170HP

CFD - Central Forge Division.

I'll let others tell you about the codes on the trim tag, but you can google those codes yourself, if you'd like.

You have a 1971 Cutlass S my friend and that plate you're describing is called a 'cowl tag' It means

ST71 - 1971 model year
3 - Oldsmobile division
3687 - Model and body style - Cutlass S Holiday coupe
G - Production factory - Framingham
62528 - Body number assigned by Fisher Body Works at Framingham. Not related to VIN
TR937 - This is the interior trim code/color/material/stitching pattern. Color is Ivory
PNT 75 A (The R you're talking about is the first letter of the PNT) Upper body color - Matador red, white vinyl roof
05A - Fisher body assembly time/build. This car body was assembled in the first (A) week of May (05) 1971.
Are you sure that's all that's on the cowl tag? No A51 or A52 by the TR code?

This is the car's VIN. (Vehicle Identification Number) It's what you need to register the cars tags.
It's pretty similar information except I think you made an oops documenting it.
3 - Oldsmobile
36 - Cutlass S
87 - Holiday coupe
1 - 1971 model year
6?? No, this should be G - it's the Framingham production code letter
123786 - Production sequence at Framingham. This is a later production model. Typically the last cars of the model run were at the end of June/early July.

EDIT: Ooops, I wrote 557265 by mistake. Eric's got you covered

Nothing significant. All blocks were cast at CFD (Central Foundry Division). So were intakes and exhaust manifolds. The other castings are time date stamps.

 

I attach a picture of the cowl tag in this post. Maybe you can se some more stuff?

 

Thanks for the answers. I have a facebook page about my car. Its kind of a blog where i document everything i do on the car. Ill be glad if you could take a look at the hood and the grill. I was told that its a front of a -70 cutlass? Is that the case?

Yes. You have the hood, grille, bumper, and radiator core support from a 1970 Cutlass. All these parts need to be swapped to change back to 1971 parts. The fenders interchange from 1970-72, but there is a subtle difference between the 1970 and the 71-72 fenders. If you also have true 1970 fenders and there is no rust, they are worth considerably more than 71-72 fenders to restorers.

 

Thanks for all information guys. So i just have 170hp Any idea how i can get more power ? I was thinkin of putting on headers, what do you think i should do to make the car more fun to drive?
