Would this block number be a 460 cid?

 

engine block codes are just above the starter. or you can pull a code off of the intake manifold to identify what engine it belongs to.

 

What you have listed there is a partial VIN number. For a numbers matching restoratio, it would be important.

I don't remember for sure, but the first digit represents the year and not sure what the Letteris for (might be the product line, if so, the G is Mercury Comet, Cyclone, Montego, etc).

 

Thanks to Airharley and Juststrokin for the replies.

 

Then block casting numbers are on the passenger side of the block are just above the starter.
The heads casting number are just above the spark plugs & just below the bottom lip of the valve covers.
Inside the valve covers is the actual Date of casting code.

The Intake manifold casing numbers are just in font of the carb on the intake.

Look for marks like this

 

The casting number listed in the first post came from the intake manifold. We are trying to determine the displacement and year of the engine. Thanks for all of the help so far guys.

 

All 429 and 460 blocks are the same stock bore. The casting number above the starter others have pointed you to will tell you what year the block was cast, actually what year the casting design was accepted for production. Only the casting number will tell you that. The VIN states year of production for the vehicle and what components it was originally equipped with.

Block casting numbers

C8XX-XXX - 1968
C9XX-XXX - 1969
DOXX-XXX - 1970
DIXX-XXX - 1971-1978.

Look on the crankshaft for a 2Y or 4Y stamping. That's usually on the front throw.

4Y - 429
2Y-XXX - 460, 1968-1978, internally balanced
3y-XXX - 460, 1979- externally balanced
