    Hi again SK,

    There's really no "shortcut" - here's what you do:

    Wait until the engine is cool, then drain the coolant.
    Take the old manifold off.
    Clean the mating surfaces on the cylinder heads and the ridges on the block.
    Install new gaskets and apply some sealant on the block ridges.
    Put the new manifold on and tighten the bolts evenly to the specified torque.
    Put the carburetor on and connect the fuel line (and any other hoses).
    Refill the cooling system.
    Fire it up and tune it so it runs nice!

    Oh, I forgot - get a Haynes manual for the car first! All this info will be in there! Good luck!

    Hi SK,

    Generally, intake manifold removal and installation labor times range from 2 to 4 hours. Keep in mind that's for a pro mechanic. Cleaning the mating surfaces of the heads can sometimes be the hardest part! Don't worry about the time factor - the most important thing is that you do a good job and learn everything you can from the experience. Since you're installing an aftermarket manifold, the tuning factor will come into play, which could make the job take longer.

    I'm not real familiar with the 343 V8 - it's a 60's era AMC, right? So we probably don't have a manual for whatever vehicle it's in. Does the distributor pass through the intake manifold or interfere with removal of the manifold? If not, then there's no need to find TDC, since the distributor wouldn't have to come out.

    Let us know how it turns out . . .

    Hi SK,

    Well, you're in luck - we have an old "Motor's" manual in our library - they give a torque spec of 40 to 45 ft-lbs for the intake manifold bolts on the AMC 343.

    When you tighten them, do it in two or three stages. Start with the bolts in the center, then work outward in a criss-cross pattern.
