    lbz to a lly engine swap -- no start condition

    Check your fuel return at the CP3, injectors, and pressure relief And I don't think you're getting 6000-8500 psi before cranking. Usually the most is a few hundred. Then it goes up as you crank. If it doesn't go up, you either have an air leak or restriction on the supply to the CP3, excessive...

    Fixing my LBZ/ truck build

    There's no gasket or seals between the to flanges. I like to use a healthy amount of Anti-seize on the mating surface and inside the v band clamp. Helps it seal up better and clamp tighten up without binding

    Bought, wrecked, rebuilding a 2009 LMM

    Calculators can be found under the "Duramax Tuning, Logging, and Gauges" section. There is a sticky called "calculators" that has it in there along with another sticky called "timing calculator V3" that has much discussion on the topic
