    Probably going to do something like this, but the intake is plastic.

    I have not verified yet, but apparently the intake has an o ring installed threaded hole to tap into.

    Also looking at flywheels, seems I can use any chevy flywheel, or maybe only the 96 to 2000 blazer/s-10 ones. Cant quite figure that one out. Also the crank hole is like an inch in diameter. seems that a sealed ball bearing gets installed. I hav never seen that type of bearing. generally sintered bronze or oilite type.

    Parts are readily available though! Not super expensive either.

    Is this where the vacuum hose for the brakes attach to the intake?

    Looks like that might work.
