    (390 fe, hei dist with msd 6a, comp cams CCA-CL33-224-3, 7105 edel intake, 670 quick fuel brawler, fmx transmission) I recently put a new quick fuel carburetor on my engine after not being able to fix my off idle hesitation with a street avenger.

  2. Choosing a cam for RPM Range

    Hotrodding Basics
    What is a good RPM range for a muscle car? A lot of the cams I am seeing have a operating range that start around 2500RPM or higher. That seems really high to me for a street car. Does the operating range of a cam dictate the idle speed of the engine as well? If the operating range of a...

Added 5 gallons of gas, put in 1/3 bottle of 103 octane booster, put some Gummout cleaner, & most of a bottle of heet drygas. ran...

    Hotrodding Basics

  8. Silverado Idling problems

    Any ideas? I inherited a 2000 Silverado with a vortec 6 litre. Before receiving it, the exhaust was re-done and cats removed. The check engine system was disabled and cannot be read. When the truck is cold and in gear, the idle jumps up and down, and will eventually die. The idle is fine in...
