Rebel 1
Les,
Hersh will probaly chime in here and add a bit.
At the moment the only engine that is acceptable in the GT40 is the 4.6 quad. Robert is currently widening and developing the GT40 for that engine.
As you know that engine and the LS1 are the only options for Cobras at this time.
Where to from here with registration is anyones guess.
