    Don't overlook the basics when it comes to engines new or old: Fuel, air, and spark.
    1) Replace your plugs and wires as a set.
    2) Look at your existing plug brand and part number and try to replace with the same.
    The wrong size plug will prevent your engine from starting. (Brand new rebuilt engine with wrong plugs = crank and no start. Looked up factory plug specs and installed, started right up.)
    3) Confirm the gap.
    4) Anti-seize the threads before installing.

    Quick delivery from vendor. Looks exactly like the original, however plugs are made in Mexico. Noticeable improvement in performance.

    I had to scour the forums for a recommendation for a set of plugs. Bottom line is for old school American Muscle, it is best to go with what was designed for the car and that is AC Delco

                  Buy at least 1-2 extra. They break pretty easy. Works good with GM products.

                          This could possibly be the problem. However, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest that you take your vehicle to a certified mechanic for further diagnosis.
