It's going in a 1947 Hacker Streamliner.
I do antique wooden boat restorations, and this one I just finally took off that wooden mount after a year of having it and put it in.
It's a 1940's Rolls Royce Merlin V12, with the Supercharger removed and two marine Zeniths in its place and other marinizing equipment. SHould be good for 700ish HP. This one was originally in a Sherman Tank. Repainted and rebuilt, there's a guy back East that sells them out of his collection and he puts Marine Equipment on them and converts them.
The motor is all aluminum and weighs about 1200lbs.
