Carmine, no I am not trying to collect / hoard them, or purchase for resale. This is a very short run. They will fit other cars however they are primarily for 1965 409's. They were only built early 64 to somewhere around end of February 65 depending on who you ask. Basically because the 396 came in either the last few days of February 65 or early March, they became obsolete. They were made for the 65 frame and 409 engine only. Because of that, I want a nice backup set is all. It's my own fault. I passed on several really nice sets awhile back that were fairly priced, now I have only seen ok to lousy since then in about the same price range.
