901 engine dimensions, specs wanted

[krl]

Hi people.

I've got a bunch of questions about 901 engines: (not the new 911 engine, but the ones used '68 to mid/late 90s)

How big are they: width (valvecover to valvecover), length (flywheel to back ?), height (oil "pan" to top of fan) ?

How much do they weigh ? Do the large displacement engines weigh much more than the small ones ?

How big is the clutch/flywheel on a 901 engine ?

Does the cooling fan push air over the heads or pull it from underneath the car ?

How are they at staying cool in hot applications at moderate power ? What about when they are turbocharged ?

What direction does the engine turn ?

What is the biggest displacement 901 one can build ? 3.4L ?

How "thick" is the pancake, ie if it wasn't for the fan, intake and exhaust, how thick is the rest of the engine ?

How far does the "oil pan" (I know it uses a dry sump system) extend below the bellhousing circle ?

How many amps does the alternator put out ? (It is built into the fan, right ?)

Are they all SOHCs or is there a DOHC engine ?

Which engine parts are aluminum and which are steel ? Are the cases aluminum ? Are the cylinders ? Are the heads ?

If there is a FAQ somewhere answering these questions, let me know.

Thanks.
