Hey there ppl!! I'm new to this site, and I have a 1990 marrow with a TBI 5.0, and I have NO IDEA on how to make this better for the least amount of money, I have a lil baby n I can;t really spend alot of money all the time. any help would be reeaaallllyyy appreciated, thanks!!!    

Got a 305 RS myself. Working on swapping in a 400 HP 350 for the 305 over on the Super Chevy website.

Being on such a limited budget, you don't have many options, but you do have some. The first thing is to get a performance chip from Hypertech or Superchips for the car. That'll help a bit. The next best thing is a cam swap. Both Comp and Crane have 305 specific cams that offer good better than stock performance.
