    I have a 90 k5 with a 350tbi and I need to replace the lifters in it and I figured why I was at it, thinking about putting a cam in it. The motor itself is stock all I have is exhaust, k&n filter and throttle body spacer. What size cam should I put in it or should I just keep the stock one what is your guys opinion. thanks

    Might as well throw a cam in it while you have it open.
    Just make sure you get a cam that is computer firendly.
    The stock computer chip will usually work with cams that have less than 214 degrees duration and lifts around .450 or less. Cams that are designed to make power from 1000 to 4500 usually will work well with the computer.
    Edelbrock, Comp cams and Crane all sell pretty good Computer grind cam kits.
