1970 350ci W-31 V-8 4-speed removed from a 1970 Cutlass S Holiday coupe (production figure is 1029), making this ultra rare in my opinion. When was the last time you have seen one of these motors for sale? How many had a factory 4-speed?

Rare piece! GLWS

 

I am looking to sell whole but will consider parting out if I get interest in each of the parts.

 

Kool find. Was the original body unrestorable?

 

Well I guess some have different views on restoration. If the VIN and data plate is present, any car is “restorable”.
anyway, northeast car. All the typical rust and more. But engine is all original. Lucky for leaky gaskets. Damper is in terrific shape. So the engine bay was protected well from the elements.

 

Still available. Someone has to have a 70 W31 project out there???

 

If you havent already, posting this on the various Oldsmobile Facebook pages should get you a lot more interest.

 

Cool engine, GLWS.
