What vehicle are you needing this for. I am assuming you are wanting to match a factory look.

No factory look here. I am putting the 408 into my 75 Valiant. I would like to put a decal on the air cleaner. I quests I could have one made, but it would be easier to buy one.

This one was custom made. I think that is going to be your best route.

Looks great! That is just what I had in mind. How much if you don't mind me asking?

Core, that design is not my own, but one I found when searching on Google.

What you could try is to buy a 340 decal similar to this one off of ebay.

Take that to a local vinyl shop and see if they can scan it and move the numbering around and copy the font of the 3 and make it an 8.
