How do you tell if the inline six in a 65 is a 170 or a 200? Is there a # somewhere or some thing to look for? Also how can you tell a 64 from a 65, or is the title the only way to be sure???

 

The title is no way to tell for sure, as the motor could have been changed.
If the 5th "number" of the vin has a T is was a 200, if it had a U it was a 170.
If the motor still has the tag on it, it will have the CID on it.

If you want to know if the car was a 64 or 65 the door tag will help, the date code will tell you. Also the general parts on the car were different for early or late models.
