>>>Sorry, but no.   All the GT40 replicas normally use a full-size clutch, 
which creates horrific ground clearance problems.   Look underneath a 
Superformance car, for instance, and you'll see the flywheel/bellhousing only 
inches from the ground, just like a Mangusta.

>>>All use full-size clutches.   The whole point of the discussion is to 
maximize the benefit of a dry-sump conversion.   There is no benefit to JUST 
inverting the ZF, if the flywheel is the same diameter as before.   The 
benefit is only realized when the gearbox is inverted AND the flywheel shrinks, 
which then lets you lower the engine that much closer to the ground.

mounts the engine higher than an original GT40 to provide for better 
clearance, while SPF mounts it in the stock (or close to stock) location and 
people beat the hell out of their bellhousings and flywheels.   I recall reading 
of at least one guy whose engine blew up because he ground it out often 
enough that he ground the bellhousing away, and the next time he hit the ground, 
the flywheel dug into the pavement and the engine went from 5000 rpm to 
STOPPED instantly.
