Not a hardcore Oldsmobile guy. I recently purchased a 1970 cutlass because it was a solid car runs/Drives and I do love the looks! If anyone has good reasoning to stop the drag car build and sell to the owner she deserves, I will start a different project out of respect for rare cars. I would like to know a value though if its worth anything at all?
1970
455 4 barrel carb
E stamped heads
th400 trans
posi rear end I have not checked the gear ratio though.
cruise control
dual exhaust still original!! rusty as a hell but still holding up!
Back fender exhaust cut out as well.
a/c
there is a tag on the drivers door that says 442
original sx emblems came with all the trim in a box.
Manual windows though.
Bench seat
column shift
car is not restored
odometer say 40,000 miles and is believable with the minimal body rust! original floors not a single hole in them.
I literally drove this car home. The guy took the car to church on Sunday, That's what I was told anyways.
I have not found a build sheet for the car. Not in the seats and the tank has been dropped before and I cant see it. I do have the bumper off.
I would like to know what its worth restored and what its worth current condition?
Any help to pave the way for this ride would be awesome! thanks very much everyone for any help.

It is going to be hard to make any judgements without pictures.

I was just talking in general. I kept seeing online sx cars $75,000 etc and it had me thinking I was making a mistake. After going through the fs section I found a few with fairly cheap price tags unrestored. I think I got my answer. Drag car here we go ha. Just not sure why people clone this car.

$75,000 restored no, but $15,000 for a nice one isn't unreasonable. If it were a numbers matching SX I'd sell that one and buy a plane jane Cutlass for about a third the price. Build your drag car out of that instead. But it would make a difference if you verified the engine is correct to the car. The SX was based on the Supreme body style, generally shaped like a Monte Carlo of that vintage. The 442 was on a Cutlass S body style, a fastback model more like the Chevelle. So if you have a tag that says 442 on a door but its the Supreme body style the door has been swapped. If you have the fastback body style then the SX emblems are from a different car. If you really want help identifying it then pictures would make a difference. First, which body style is it? Second, photograph the trim tag on the firewall above the brake master cylinder. Then look for the vin on the engine block and transmission, we can show you where to look for that. Since your a car guy you understand the value difference between a numbers matching car and one cobbled together. So... if you want help identifying things before you cut it up let us know the questions I listed, and yes, photos can make a big difference. John

will do. Its the monte carlo style. I will post some updates tomorrow. Just knowing what it is I will likely just document the car and do nothing I cant reverse. The plan is twin turbo 455 low boost, FItech fuel injection etc etc. The car right now is a 10 bolt posi I found a little odd my self? Thanks for the help!

The vin derivative stamped on the engine is on a small pad below the letter E cast in your drivers side head. Here's a thread that has some photos showing where that's located.

The vin stamp on the transmission is on the drivers side. I've seen both stamped on the horizontal and vertical planes in this location.

Then this thread discusses an SX I came across in 2013. It has a photo of the vin on the transmission of that car. Its on the vertical plane of this transmission.

Check the ID tag on the passenger side of the T400, it can be an OD or OG for the SX. OD would indicate a base SX, OG indicates the W32 version, as long as the VIN stamping matches the car. Total SX production was around 7700 for 1970, with about 1000 of those were W32 versions. These cars still dont bring what an equivelant 70 442 would sell for, just the nature of the beast, people would rather own a 442 than a Cutlass Supreme.
If youre building a drag car, a Cutlass S or F85 would end up being a lighter car, and a solid SX should be saved even if its not restored

One more comment, you said it had a 10 bolt rear end. The 1970 A-body would have come with a type O rear end. Oldsmobile only rear with 12 bolts on the inspection cover and 10 on the ring gear. But this is a bigger 10 bolt than the chevy/Pontiac/Buick 10 bolt of the era. This ring gear is about 8.4-8.5 inches across rather than the 8.2 used by other GM A-bodies.

If it doesn't have a round inspection cover with 12 bolts holding it on then its been swapped out over the years.

I didn't know about the transmission tag code on the SX. Here's a picture of the OG code tag on a 1970 TH400

I agree with the previous posts tha if it's a real SX then sell it of profit and buy an S or F85 for a drag car. I have never heard of such a thing. The door tag would have the VIN but the body style would be on the cowl tag. As previously stated post pictures and we can give you feedback.

He may mean there is a 442 badge on the fender.

I think my 1969 has a decal for air pressure in the tires that says 442 on it. Its on the end of the door above where the blue tag would go on the 70-72 cars. Maybe something like that? Maybe something a previous owner stuck on that's not factory?

vette442

If it's super solid and a W-32 it definitely worth selling for a profit and finding a base Cutlass Supreme to highly modify.

As a Vette guy, think of it like an 1969 L46 Stingray - it's not a 427 (what the masses crave like a 442) but it hauls *** compared to the base 350 and carries extra value. A W-32 SX (or any SX) is far more rare than an L46 Vette though and has its own cult fans.

the 442 inside the drivers door is the tire pressure recommendation
I could not find any tag on the drivers side of the trans that said o or g
the rear diif cover has 10 bolts. Still yet to be identified. Is this not correct for a cutlass supreme sx?
Still have to check all VIN numbers match etc. really just interesting trying to figure out what the history on the car is.

The trans tag is on the passenger side of the transmission, the VIN stamping is on the drivers side.

It is not correct for a 1970 Lansing built Cutlass.
