Since it's in the car, perhaps the easiest way is to get the casting code off the engine. It will be located back by the distributor. There are several online sites that have the casting codes for a Pontiac engine.
the easiest way is to use the 8th character in VIN number to find out what engine it is. another way is look under the hood, usually they put stickers that will have your vin and the engine size i.e. 4.3

Different engine call for different plugs. You need to BClear as to what you have. Look under the hood for a white sticker, It will identify you engine size as well as the gap for the plugs. Or call a parts store.

define engine cc size 246cm
2.7 liters is the displacement (size) of the engine.
you go by the serial # on the car or you can look on the engine block on the side of the engine for the serial # of the engine.
Take the VIN off the dash and call your Ford dealer; one of the characters will identify your engine size. Also under your hood the will be a ID number which should indentify the size. Serial numbers are ususally located on rear of block near the bell housing.......1930fcoupe
If it's the original engine use the VIN number and go to your favorite parts supplier and they can tell you. If it's been changed you have to get the casting number and do some research. Or go to your garage and ask your mechanic and he will be able to tell.
CC (cubic centimeter) is a measurement of displacement used to identify the size of the combustion chambers in an engine. HP (horse power) is a measurement of power the engine can produce. CC and HP are not the same.
