Mopar part # P3690982
http://victorylibrary.com/mopar/weiand-c.htmI bought it on E-Bay June of 2013. I also got kind of lucky, his reserve was not outrageously high, the auction ended mid day on a weekday, and there were no other serious bidders. I had been keeping an eye out for one for several years, they are not easy to find. Mine was new, I had the seller ship it to Bruce at F&B Performance who did the EFI conversion.
http://www.fbthrottlebodies.com/Bruce will sell you a brand new 440 6bbl intake converted to EFI in the same fashion. Should be no issue with hood clearance. But, this is not a tunnel ram. This is the EFI set up that is on the Year One '69 Road Runner 505ci engine.
http://ghostworks.yearone.com/1969-road-runner-convertible/The Weiand tunnel ram intake has runners tuned for a 440. The runner length is too long for a 500ci engine, unless you were building an engine for a truck used for towing.
EFI likes camshafts with more LSA (112-114) and good idle vacuum. Makes it easier to tune. Not impossible with lower LSA, just not as easy. I am looking forward to tuning mine. 108 LSA and solid lifters.
Found a better picture:
