If you are buying a "kit" from them, maybe they supply the injectors, MAF, etc.? I would find out exactly what all comes with the SC before purchasing anything else.
The stock 5.0 block is of a thinwall casting design and relatively weak.
They are known to split right down the center of the block with too much boost or a bad tune which allows them to detonate under boost. Anything over 500 HP and you should consider adding a Main
& Valley Girdle
to the block to help stiffen it. This will greatly increase the block's rigidity, life expectancy and should be good up to 650+ HP, IF the engine is kept properly tuned.
Increasing the air flow into and through the engine with the SC will be benefited by increasing the size of your air intake system, ie, the air filter, air intake tubing, MAF
& throttle body. However, don't go overboard, size the items as needed to work with the engine intake you are using and horsepower levels you want to achieve.
On the other side of the engine, a properly sized set of headers and exhaust system will provide further benefits and increased power by allowing the spent gases to be exhausted more efficiently.
An increase in injector size will be needed to supply the additional fuel required by the increased airflow. You may also need to install a larger fuel pump to ensure adequate fuel flow. Holley makes a 255 lph EFI Pump
that is specifically designed for supercharged engines.
Tuning can be done by using a chip as stated above or a tuner. Tuner choices are somewhat limited for the 79-93 Fox Body Mustangs, but they are available. One choice would be the AFM PMS
