-Ford 5.4 331 cu inches at NHRA maximum specs will be 342 cu inches
-Chevrolet 350 cu inches at NHRA maximum specs will be 370 cu inches
-Mopar 354 cu inches at NHRA maximum specs will be 374 cu inches

Now coming into play, adding another 2 atmospheres of air with the use of a supercharger at approximately 26 psi boost.

Ford 5.4 NHRA max specs 342 cu in with 2 atmospheres of air is 1026 cu inches
Chevrolet 350 NHRA max specs 370 cu in with 2 atmospheres of air is 1110 cu inches
Mopar 354 NHRA max specs 374 cu in with 2 atmospheres of air is 1122 cu inches

So under boost Chevrolet is 84 more cubic inches and the Mopar is 96 more cubic inches than the Ford engine combination.

The 2.9L front entry Supercharger spinning to 9,000 engine RPM will produce 26 psi boost in both the GM and Mopar.

The 4.0L Supercharger with the 4.00” pulley on it at 9,000 engine RPM will produce 24 psi boost on the Ford 5.4L motor.

Some say the Ford has a better flowing set of heads which is true but we are limited with camshaft lift. Which the 500 and 510 HP combination only have a .471 max lift cams.

GM and Mopar are well over .640 max lift cam specs, which allows there heads to flow more.
