In 1958 BMC produced a high performance version of the MGA called the twin-cam. This used a new aluminum cylinder head on the B-Series engine to produce 108 bhp.

Along with the DOHC setup, BMC also fitted Dunlop disc brakes and Dunlop steel wheels.

All the twin-cams are easily identified by their Twin-Cam logo near the side vents.

Due to detonation, the compression ratio was dropped from 9.9:1 to 8.3:1 on the later cars.
