Strip it down, make a 5.0 based on the 4.8 truck engine, make the block aluminum since ford already has their 5.0 in order. Watch Dodge follow suit making the 4.7 a 5.0 and then they slide it into the Heffer, er I mean Challanger....BAM, instant Trans Am race series 21 Century style.
( making mental calculations) leave the bore at 3.78, and make the stroke 3.39.....close enough.....
Tell them to do it now. kthanxbye
