Continental AV1790

The Continental AV1790 is an American V-12 engine used in tanks. Produced by Continental Motors, the AV1790 was used in a variety of limited production and pilot heavy tanks, including the M53 and M55 howitzers, the T30, T34, T43 (neither to be confused with the Soviet T-34 or T-43), T57, and T58 tanks, as well as the production M103 tank (derived from the T43) and the M51 recovery vehicle. There were also diesel versions (AVDS, automotive vee engine diesel supercharged) for the M47, M48, and M60 Patton tanks.

An AV-1790-5B is also the engine of the Blastolene Special, a custom car owned by Jay Leno.
