    98 OBS ecsb 5.3ls swap

    Hey everyone, been on this website for a while now and have gotten a lot of
    knowledge and inspiration from all of you. Don't know how long this is going to
    take but already there is a large sucking sound in my wallet! Anyways, I'll post
    my progress as I go.

    Let the madness begin.

    Here are some more pics of engine. 08 5.3. This engine is supposed to be
    a high output 5.3. Aluminum block, "243" heads, big valves. 100k miles
    bought the engine for $800. Also got a 4l80e with about 1500 miles on it for
    $800.

    I've built a engine run stand that I am going to run it on before I put it in the truck.
    Still need to tweak the stand a little, put gauges in it, battery holder, etc.

    Welcome to the site. Lots of info here and guys willing to share their secrets on swap details.

    Nice stand. Looks like professional quality. You should market them.
