    C1500 Full Protouring Chassis Build, Twin Turbo LS Swap

    I got this truck 10 years ago from my Grandfather when he passed away. I documented me doing a partial restoration on it then.
    The truck has been sitting for a couple years, so I decided it was time to dig back in. Go big or go home.

    I plan on documenting the build on here as well as my YouTube channel "Loudandproud"

    Nice! I see an Alpa TIG back there too. I have no complaints with mine. What's the thickness of the plate your using there?

    I love my Alpha Tig so far. I bought it a year ago to learn weld and have gone through 25lbs of filler and 200cf of gas so far. No problem.

    The crossmember is 1/8" thick material. The crossmember is 6" wide and 2" tall at the thinnest. The inner support tie the vertical of the crossmember together and reduce buckling. Upper the strength by almost 35% on my FEA results.

    Photos went up in wonky order. I got my fixture plate made up for the lower control arms. Looking nice. The 3D printed bits have tabs on the bottom that locate their position in the plasma cut slots. Next week I will be picking up some tubing and will be taking the virgin run on my JD2 bender.

    The steering rack is on. It's a quick ratio fox body rack... I plan on running an electric assist column. If it sucks I'll convert to hydraulic later.

    Moving along...

    It's a great street truck.

    Last week I got the cross shafts for the lower control arms. I couldnt fit standard bolts in past the steering rack, and I didnt want to pull the rack in order to adjust the lower control arm lengths.

    Completed the lower control arm fixturing as well. My 3d printer is going on the fritz. Yay!

    I got my tubing bender set up and some 1.25" DOM ready to go.

    Lower control arms will be done soon.

    Made a fair amount of progress over the last week. Got one lower control arm complete. It is made of 1.25" 120"wall DOM and uses a K772 ball joint sleeve with 5/8" rod ends (urethane bushings).

    The coilover mount is 1/4" plate. A little heavy duty but weight reduced down to under a pound for both brackets.
