If it has the original air cleaner assy and it hasnt been peeled off there should be a label or sticker on it if its there you will see it clear as day you shouldn't have to look for it but if its a V8 chances are its either a 305 or 350 its the 8 digit on the vin nuber that would tell you im sure you can give that to any auto parts store and they'll be able to tell you
