Which Big Block is Original
 

OK, how in the world can you tell what motor originally came in a 1968 Nova. I decoded both the Data Plate and VIN tag and both simply tell me it's a V-8 car. How do I know if the motor in the car now (which is supposeably a 427) is original? Just judging by appearances it looks very original, but overall the car is rough and before I lay down my hard earned money and begining restoring it I want to make sure the car is worthy.

The largest displacement you could get from the factory in a 68 Nova SS was the 396/375 HP motor. You can not tell from the Vin or trim tag which motor the car received. It will only tell you if it is a V8 or 6 cylinder. There was at least one Supercar dealer that installed 427's in 68 Novas. The Vin #'s of those cars are known and are listed on this site.

Do you have any photos of the car that you could post.

If the original engine is gone, you will need to confirm via paperwork or circumstantially via a list of items signifying a particular engine - L78, L34 or SB.

I saw a sticky with VINs for 1969 and up vehicles but where is the list of 1968 vehicles?

Nickey Chevrolet/Chicago converted many Novas to 427s and 454s.
