I've got one - on an RB running Indy EZ Max wedge ported heads. Bought it as it's about the lowest single plane intake you can find and has bosses that are easy to machine for injectors (I have a port injected EFI set up.) Fits great under my stock 63 Fury hood but I reckon you'd probably want a big spacer if running a carb.

At some point, I'll take it off again and get the valley tray portion cut out as it's redundant at the moment.
