well i know that the bore and stroke are both 3.55" so that answers Q 1&2

for Q 4-6 just get a PI swap from the 99+ GT's you wont regret it

wow that was helpful.

from muscle mustangs and fast fords:
'All 4.6 engines have a 3.552-inch cylinder bore and 3.543-inch crankshaft stroke, making the engines essentially "square." '

also, go to here http://users.erols.com/srweiss/tablersn.htm and scroll down to Ford V8, 4.6L. The guy has a whole lot of engine specs compiled for just about all car companies.
