    8.1 vortec into 1979 k30

    Big blocks can get expensive. My tall deck 8.0l build cost me a small fortune. 8.0l was the gen6 with gen7 parts sprinkled on it. Rods and pistons are the weak points on 8.1l. Raylar heads supposed to perform very well from what I have seen.

    8.1 vortec into 1979 k30

    Interested notes on parts compatibility. With a specific gm crank, rods and pistons swap between gen 6 and 8.1l. Cams are also direct swap but different firing order

    700R4 nightmares

    Either make sure axles regeared and have a good 700r4 build, or switch to 4l80e or th400. If it is monster transmission , I would avoid their build.

    Important when put together to adjust for right amount of play. Can either use specific tools, or works well by feel. Feel how it goes through the center.
