FORD GT40 RESTORATION

The Motivation

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.)

Let's start by disassembling and cleaning:

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.

Figure 16 - This is a new old stock "Mirage" 351 block, complete with 4 bolt mains and raised deck height.

Figure 17 - Another NOS "Mirage" 351.
 

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.
