Update: It's the Lycoming XR-7755-3 from 1945 and it is on display at NASM's 
Udvar-Hazy Center at Dulles Airport. 7755 cubic inches.

I also like the Napier Nomad II Model E. 145 on display there. Flat 12 
diesel, injected, supercharged, turbo-compound (the exhaust gasses spin a 
turbine that turns the crankshaft through a fluid coupling); quite possibly 
the most complex recip aero engine ever made.
