    Update. My shop is pretty much done on the inside and I have all my crap in there finally.
    SUCH A RELIEVE to finally have a lift.
    That was a lifelong dream.
    So I am working on the 72.
    I pulled all the brake and fuel lines.
    I replaced the brake lines already. Since I have a 9in rear end I just did all lines myself.
    I also put in a new 9in brake booster and Master cyl. + a adjustable proportioning valve.

    Next thing is to put in a AC blockoff plate.
    And route the LS fuel line kit with the C5 fuel Regulator/Filter.

    Engine. Trans (4l80e) are in .
    And I have to say the holley /hooker mounts and trans crossmember are a huge relief.
    They work perfect!
    Rather spend some $ and safe the headache.

    I blocked the firewall.
    Installed Speed engineering 1-7/8 long tubes they needed a bit of BFH massaging to clear the eng. Crossmember but that was easy.
    All in all I'm very happy.
    Further I installed a 20 gallon fuel cell with a 450 internal walbro pump.
    All new -6AN braided fuel lines, a c5 corvette style regulator and return.

    I am debating if I should use the standalone harness and flashed ECU or invest in a holley terminator x max.
    I know it's much easier to tune etc.
    But the costs would also cover my (probably vintage air ) AC setup I definitely need in this TX heat.

    Use a factory computer and a Blackbear remote tune via data logs and emailed tunes. I’ve done 5 this way using the “auto cal” option.

    I put in the headliner, package tray, rear door panels (mod. For the harness bar)
    I think it looks pretty good. This where used panels I got of a member on here.

    Also got the chromoly 7.400 pushrods in the mail and installed them right away incl. Rockers

    I modified the alternator bracket and deleted the power steering. I cut the bracket and added a pulley and used spacers and bushing to convert the 17mm hole to a 10mm. Got a 82.5 in belt for it & It lines up perfect with a couple additional shims.

    Ohhh how I hate wiring.
    The car has a aftermarket fuse box and harness already. Unforthunaly I dont have the part# or manual of this harness but the wires are all color coded and labeled.
    I still hate it FML.
    So i organize it 1st. And loom it. I hate crappy wiring .
    I am by any means no pro. But i try my best
    So i also made a relay panel with 5 switch option. That fits perfect in the glove box. 20200818_111606.jpg 20200818_111524.jpg

    Got the fenders and hood on.
    The hood clears even with the high intake, using all holley mounts.
    I slap a scoop on anyways ;)

    I was in the "zone" this weekend and knocked out the car harness (engine bay) + installed the standalone LS harness.
    Further I built a bracket/mount for the PCM,a battery bus bar & a relay panel ( in the glove box) that will be controlled by a 5 switch panel that has USB and 12v charge as well.
    I build a bracket for the radio opening since I plan on running a bluetooth amp. Only for the "radio".
    As a "dash" I am planning to use a 7" tablet .
    With a OBD2 app for the gauges.

    Yeah, you can get some HP with a turbo. My son & his friend started with a 2014 LS 6.0 that started at about 380HP that had a cracked block my son fixed. EXCEPT for head studs, better head gaskets, his own ground cam to his specs. & valve springs using stock hydraulic lifters they are now at around 1300HP. Original rings, pistons, pins, con rods, all bearings, etc. etc. in a 3200pd. '91 Mustang have run a best of 7.77@178MPH. Docile enough to drive on the street, is registered & insured, has 3.23 gears & in street tune with street tires can get 20MPH.
    Not bad for a mostly, completely stock LS3.

    LS motors respond very good to boost and its nothing special to reach 1000hp with a 5.3 truck LS and Turbo(s) and it is very tempting.
    But i decided i want a NA LS and keep it reliable and "basic" my 68 GS is a Twin turbo sbb. My truck is a tuned F250 Powerstroke, so i have boost arround me ;)
    Maybe i change my mind later for the lark but for now it will be NA.
