more power from a 95 sierra

I have a 95 sierra 1/2 with a 350 and a getrag 5 spd trans. I want to give
it more power it has a 3.08 gear ratio in it and would like to go to about a
3.42 posi unit. Besides this what will help And what issues will go along
with the gear change ive read about the drac-vssb board but i dont know if
mine has one.
The truck is a mid year it has the 96 interior in it but has the old 350 tb
injector on it not the vortec. So would i have to modify the box or what?
THANKS ALL to those who reply and sorry for the stupid questions

Antilock brake system is going to have a conniption fit. System compares
rpms of the front wheels, to the rpms of the rear axle sensor to the speed
of the vehicle. when you change the gear ratio nothing is going match up,
so that aspect of the swap will have to be addressed. First, find out if
that axle ratio was available that year, and also take into account the tire
size you are going to run, which will also affect the system.. most of the
time your local friendly dealer can make changes to programming fix the
problem.
