what are some rather inexpensive mods that i can put on my car for the best gains in horsepower and best potential?

 

intake

 

intake is a good one also i heard of the chip, spark plugs and there wires, umm if u can bend pipeing and weld or braze you can make your own exaugst i did my own on a 1973 nova just go to lowe's and pick up some fence posts

 

try to mods. as much as you can, then get the chip'.
