No. The service Short Block from Ford is the same as the original; it’s not designed for positive displacement. If it’s your weekend toy and you have money to replace the engine again, that’s one thing, but it’s certainly not an ideal scenario. Especially if the engine comes apart and debris is ingested into the supercharger; then you’re out both.
The bottom line is the 6.2 doesn’t breath well N/A and F/I certainly doesn’t make that any better. You’re trying to force air through a 2V engine that existed only to serve as a base gas engine to supersede the 5.4. So everything from the pistons to the cylinder head design to the rods, crank, and cooling system are only designed to for atmospheric pressure at the most, not a positive air charge.
As others have mentioned, the oil pump is the first weakest point, as it’s not designed to handle the load the S/C drive puts on the crank. When they fail it’s a total engine loss, so that’s a bare minimum upgrade.
The pistons and rods are the next failure point, same scenario as above. The cylinder pressures from F/I are immense, especially at low RPM, which can result in connecting rod failure. The piston ringlands are are susceptible to cracking/failure and cylinder wall damage due to excessive heat buildup, detonation, and pre-ignition. Hence why the Livernois long block uses forged pistons with thicker ringlands.
With the Livernois long block being $20k, the S/C kit being $10k, and then a few grand in labor and tuning, you’ll never recover that investment. And then your next weakest point becomes the transmission, t-case, and axles. Putting down the power that the livernois engine is theoretically capable of is simply not going to happen with the stock driveline or suspension, especially since you’re limited to 2WD with their being no full time 4WD mode.
People will tell you the original engine is “fine” and not to worry about it, but they’re not the ones footing the bill when it fails. And last we’ve heard, long blocks are no longer available from Ford.
