    Truck stolen.

    Spare keys? I’ve owned a vehicle for 15 years and never had an issue. Worst comes to worse break a window to get in they’re cheap.

    Truck stolen.

    I disconnected the rods from the key lock to the lock mechanism. I figured that way it would make it a little harder to get in.

    LLY - Cracked piston

    I would do 100% injectors. AF crank isn’t necessary I would just make sure the crank is balanced good.

    2015 LML DenaliHD keeps moving after coming to a dead stop during redlight

    My grandparents 4 runner would do that. Would be sitting at a stop, you would hear a thud almost like the ac compressor kicked on. Then it would roll forward. We just changed the brake pads and the rolling at the stop went away 🤷‍♂️

    Air filters for High CFM air flow?

    You’re going to need a much bigger filter, or two. My plan is to run a tube down to the bottom of the grill with to filters and build a shroud so water doesn’t get to them.

    The newer head units have wireless car play now. Not sure if all of them offer it.

    NHRA Rulebook Question

    Are swing out door bars that much weaker? Couldn’t you just make them stronger? I’ve been debating a cage for my truck but driving it every day has put me off from it.

    LLY new engine won’t start.

    Forgot to update this. The ground at the end of the crank and cam sensor harness was broken inside the insulation. Truck starts now but runs like shit.

    Starts runs like sheet then dies

    Check the ground at the end of the crank and cam sensor harness. Had the wire break inside the insulation and gave me hell.

    Turbo suggestions for 7.1 build

    Your cam is too big for a street truck. When you mentioned 9100 cam I assumed you were going for 1500hp+. I would put a much smaller on in and run a 72/87 and a 91/100 over the top. Easily make 1200 with great street manners.

    Turbo suggestions for 7.1 build

    You might be better off with a 96 turbine in the valley. Depending on the rpm range you want to run in, but judging by your 9100 cam you’re gonna be running higher rpm.

    1/8 mile discussion and time slips post here!

    Just to stir the pot. I don’t like 1/8 mile, but if it’s “safer” and too expensive to go 1/4 mile. The list should start at 5.99 🤷‍♂️

    2005 2500 puzzle

    yes the y bridge has a slip fit with an O ring. If that section isn’t supported like it was when the egr was there, the tube can and will blow out.

    Does that have a bracket to keep the Y bridge from slipping out?
