How to change gear ratio?

I have a 1980 chevy k20 4speed. The 1st gear has a low gear..is there any way to put new gears in and stretch the gears out. I was also wondering how can you increase your top speed, can you change your final drive ratio?How to change gear ratio?
Does it have a manual or automatic transmission? For most Chevy transmissions, it is possible to adjust the gear ratios but first gear is low for a reason, especially in a truck.



If you are looking to increase top end, you might be able to swap out to a later model transmission with overdrive, but if the transmission is not in need of repair, it would probably be a little easier/cheaper to change out the ring and pinion gear to lower ratio gears.
