It's probably possible, but the amount of money required would make you weep and you'd probably have to rebuild it once a month.
Anyway, the only practical way to get 300hp to the wheels (hell, even 300bhp) is some kind of forced induction. Otherwise, it'll be impressive if you manage to break 200hp to the wheels.
If your new motor is in good shape (good compression, leakdown) you can go with a turbo kit on stock internals. It'll certainly be more bang for the buck than any high horsepower NA build.
