With 96 and above will crest 400 quite easily. With a bit more tweaking, it will surpass 400 rwhp 91 octane and what's been done to the motor is considered mild in comparison. Price is reasonable and the motor is much more reliable then and FI motor, especially for everyday driving.
The problem with an FI motor, is the eternals. They can't take the pressure and continuous abuse. Parts wear quicker and are very susceptible to breakage, particularly mains, rods and cranks caused by inefficient oiling.

Your argument on FI is not 100% exact, there are a lot of variables which will contribute to internal wear & tear for both a FI & NA build.
Now onto your NA build at 396whp, what cams/rods/heads are you using? How are you tuning VVEL. What type of headers and define improved fueling.
