While a majority of the hours spent on a proper GT40 restoration
may be involved in rehabilitating the tub, the prime mover obviously
warrants attention.
(Also below you will find one of the coolest dyno pictures you'll ever see.)

| Perhaps the rarest of all GT40 engines is the 1967 "Mirage" 351 engine. This 5.7 litre engine was legal for for a brief time in 1967 before the maximum displacement rules for the class were changed to 5.0 litres. When properly prepared, the "Mirage" 351 was very fast: winning at Spa, Kyalami, Karlskoga, Skarpnack, and Montlhery. |

| Even more rare than the GT40 "Mirage" 351 block is a set of prototype cylinder heads for that engine. Based upon the factory "C6FE" racing cylinder heads (which are quite rare in their own right) these new old stock heads feature a dropped combustion chamber. This lower valve seat area allows for substantially larger & straighter intake & exhaust port runners, which increase air flow nearly 15% over the GT40 C6FE race heads. |
