I wasn't going to butt in but I think I come closest here. I have a 289 with a rpm airgap, one inch spacer, edelbrock 600 and a 2 inch air cleaner. I can push down on the hood with it closed and feel my air cleaner I would say maybe 1/4 not quite 1/2 inch clearance. Its tight to say the least. I would say if you can go with out the one inch spacer you might make it. I was sweating the whole way till I shut the hood. It doesn't look like it should fit. lol Good Luck, Latman
