A friend is building a 71 Nova for IHRA/NHRA Stock eliminator. We need a cast iron Quadrajet intake for his smallblock. Problem is, it needs to be a specific one, and I'm having trouble finding one. Casting number for this intake is 3973469. There's nothing ultra trick about this intake (in fact it's probably no different than any other cast iron smallblock intake), but class rules require this specific intake based on year and engine size. If anyone has (or knows someone that has) one they'd like to part with (cheaper the better), shoot me a pm. Thanks.
