Whats currently done to the motor to make 395HP?
Generally speaking, to increase HP, you could increase compression, install a larger cam and spring package along with port work done to the heads and possibley install larger intake valves, plus install larger diameter headers.
Or bolt on a Nitrous Kit.

Swap in a 455.
