sure ...I think the first step should be canning the Modular series and bringing back, and basing everything, off the Five . Oh / 320
the new 5.0l ( a bored out mod) is going to surprise many people - this engine is saving Ford's pants after the 6.2l came out as a failure in internal testing. The MOD might be a little light on torque under 2,000rpm, but it is a nice engine - it is not class leading, but neither was the old Windsor - which BTW is less efficient and less clean.
The biggest problem with the MOD's - tiny bore - is being addressed and the 5.0l is perfectly square and in its most basic form as a truck engine will deliver 350hp - in Mustang form 380-400hp and with DI - 425hp. an EB Twin Turbo version is also coming. To boot - in all applications is delivers impressive GM meeting mileage.
The MOD is not dead - it is actually just about to start kicking some serious butt.
Oh - and it was already suggested : 5.9l V10 - hmmmm ..
