    Default 1999 GMC Suburban 454 c.i. upgrades

    I recently bought a 1999 GMC Suburban with a 454 motor and want to get some more power out of it. I looked at several web sites such as Jegs and Edelbrock but they only list 454s up to 1995. I can't even find a site that will give me supercharger application that will work on my Burb.... Does anyone out there have any feedback they can give me on where I can start to look for these types of improvements? Any help would be appreciated.

    Hi, Welcome to the site.

    I've always had luck with Summit. This link is for a 1999 k2500 suburban w/454 4908012+4294924667+115+4294840133
    You can look for upgrades from within the drill down list

    There isn't much support for the big blocks in the way of superchargers for any year. What have you done for upgrades so far? If you haven't done anything, the most cost effective ($$ spent per hp gained) would be headers, and a new cold air intake filter kit.

    Talking Why a supercharger?...Because you can!!!

    Check with Paxton. They have an application for a 2002 BB Truck. They might be able to set you up.
