    Default Wasted Income's LSx into an Avenger Jet Boat Build

    Hey all....I've been documenting my build over at LS1tech but thought a lot of you guys may get a kick out of it as well....so I will share my story, and progress with you as well.

    I am no stranger to LSx swaps, as I've done a couple, including the turbocharged 5.3L/4L80E setup in my '69 Chevy C-10.

    Anyway, here is the boat when I first bought it.








    Couple years ago, I decided to pull the big block to freshen it up....and it turned into a full rebuild/cam swap/$$$ snowball. While I had it out, I decided to do some mocking up of my spare 6.0L LQ9.



    Out with the old....


    In with the new! 6.0L LQ9










    Lessons Learned:
    -The truck pan is ~3" too deep, and the sump is on the wrong side. Need to research what pan will fit better.
    -There is a TON of room with this LS in there, vs. the big block.
    -Motor mounts should be a piece of cake!!!
    -The old BBC Indmar bellhousing will work pretty much perfectly (minus the starter of course)
    -The drive coupler should be pretty easy to adapt. Either by re-machining the holes, or by machining an adaptor.

    Ended up rebuilding/upgrading the 454 that was in it.



    And then, the project was back on after this past September....
    Dropped a valve in the 454 and scattered it the last time out for the year. I am done with BBC jank. Bring on the LS!!








    Picked up a nice LQ4 from a local wrecking yard, complete from engine cover to O2 Sensors.

    Little dirty, but should clean right up:


    Yep, cleaned right up. More pics to follow.




    Working on getting some other parts to fall into place to keep this thing moving forward.

    She's slowly starting to get undressed





    Was a LOT of grease/grime under the intake and on the valvecovers. Here's a before and after shot.





    Went to my buddy's place and got the boat out of storage so I could actually work on it.







    LS2 GTO pan works PERFECTLY for clearing the pump....unlike the stock truck pan.

    The big block bellhousing bolts up without any problems.





    BOOYAH! Everything clears perfectly. Can even install/uninstall the oil filter...but it is close.



    Got it set into place, leveled and square, and made motor mounts.



    I fabbed up some water pump block-off plates





    Wrenching party.....aka "The Fastest Cam Swap Ever", haha.



    I fabbed motor mounts to mount to the stock mounting studs that are bolted to the stringers.

    Painted the block with VHT ceramic engine paint.

    Waterpump blockoff plates bolted up and ready to go.



    Awwww yeah!!
    The aluminum front cover and oil pan cleaned up nice with a scotchbrite roloc.

    I called up Kodiak boats out of Oregon and got an LSx PTO, and also called up REX Marine and got a new driveline to go with it. Should be the same length as my old Rockwell H-bar driveline, so the motor should be able to stay put.

    Got the cam put in...it's a Lunati from SDPC and the specs are:
    224/232
    .585/.590
    114+4LSA
    with Patriot Golds and Comp pushrods.

    Here is the cam that I bought for it:


    Still trying to figure out what to do with the exhaust. Bassett said they'd make me a set of headers for $1500. Seems pretty steep, but they have the water injection lines in them already, the Bassett T-valve, and they are chrome plated. Anybody else have any good options?

    Started working on my fuel system. For a pump, I am using a Bosch 044 for the time being. The plan is to eventually swap it with the Walbro 255 in my '69.
    I also ordered up a C5 vette return style regulator/filter that i'm going to mount right near the tank.

    Also converting over to an all car intake setup....so i get to solder new pigtails to my truck harness for injector connectors. Here's what I've got so far...I'm planning to mount the intake backwards, so that the TB is back near the bellhousing...because I don't think there's enough room at the front for the TB and intake duct/filter with the seat right there.

    I have done some reading about your build...how is that coming along?

    My B/W S400 turbo'd 5.3 LSx is a runnin motherfkr.....I would love to put a snail or two on this setup, but it's not in the budget this year.

    I can't wait to see how this thing runs in my boat. Adding 100+ hp, and removing 300ish lbs....should be fun

    wished you'd made copies of those water inlets/outlets lol i'm a shit fab guy i made me some plates outta alum and tapped them for 1/2 pipe threads, best i could do. i'm bringing in 1 5/8th water hose and splitting it, then outgoin will be 2 5/8ths hose from each top port, i don't wanna worry bout a pressure regulator on this motor, jus giving it plenty of dump and since there's no gaskets to blow, i ain't gonna worry bout it
