Engine no. 86858. Part no. AEH 37XAA This twin cam engine and proper four-speed manual transmission are very presentable, with a painted block and a variety of polished surfaces. Mounted on a custom cart decorated with real MG badges, this engine/transmission makes an excellent display piece. Introduced in 1959, the twin cam, fitted in the MGA, was the most powerful engine MG had ever offered its customers.
