Dear omnivore:
I just had a thought, to add to your idea of a turbocharged four cylinder engine in an FFR Cobra, how about arrange said four-cylinder like BMW did with their F1 engine.
They canted it over 72 degrees on its side. That makes for a much lower center of gravity, as well as leaving enough room for headers to get through (as opposed to an engine like a flat-12 Ferrari or a Porsche flat-6).
Of course, that might mean you might have to use a geared crankshaft, but not necessarily. And if you did, geared crankshafts have been successfully used for decades. You need not worry about it.
Since you will be putting the engine in the front of the car, you will not have as much trouble arranging the intercoolers as BMW did for their mid-mounted engine.
The BMW engine developed, in qualifying tune, about 1200 horsepower. That was developed in the last 500 revs or so before redline. See Innes Ireland's road test in Road & Track magazine for details.
So, for your street car, calm the engine down to a moderate 400 horsepower, with 400 foot-pounds of torque, developed from, say 1700 rpm all the way to redline.
As much power as a big V-8, minus 400 pounds of dead weight, a much lower center of gravity, and a much better weight-and-balance solution, and voila: you've got quite a car!

Don't quote me, I've not verified it personally, but I've read in several places that the SBF and Gen III/IV exhaust port spacing are identical and that you can use a stubbed header flange for the Gen III/IV motor and weld SBF headers to that.
Although its not a Cobra my entire build has been modeled after the Factory Five and the information I learned on this web site. It has a 5.0 HO Mustang motor in it now. This picture was to test fit the Dodge Red Ram. Hood clearance for the Webers is very close. The Red Ram Hemi is an expensive way to get 1 HP per cubic inch but the eight velocity stacks does have a certain coolness factor that is hard to beat.

LS6 finished in 2002. One of the first LS engine installations in a FFR. Upset a lot of Ford guys. 398 HP and 401 ft/lbs in a 2300lb car. Lots of fun. Just sold it so I would quit playing with it and finish my GTM.
