Back to the top of the thread the 1UZ has been put in several aircraft.
The new 5.0 from Ford is an awesome engine capable of massive hp. Ford have released it right at the bottom of it's potential to allow for future power upgrades. With the $ the way it is now it would have to be a must have for any new cobra builder.

The LS engine is still an awesome value power pack too but starting to get left behind as far as vvti technology goes. I do remember seeing a while ago some aftermarket dual overhead cam heads for the LS engine.
