air cleaner for a 1969 L72 427

Dave, The air cleaner you listed (6484597) is for a two barrel small block. You have to flip to the end of the Assembly Manual, page 483. I am assuming you're looking for a Cowl Induction air cleaner by the eBay link you posted. The big block ZL2 air cleaner is the same as the small block air cleaner with the only difference being the small block air cleaner uses a spacer to make up the height difference.
