    How can I tell the difference between a 283 and a 327?
    Truck has a rebuilt engine, supposedly a 327 from a '66 Impala. Was told to check block numbers. Problem is the lists I found online show 283 and 327 having same block numbers some years. Is there any way for my somewhat untrained eye to tell the difference?

      A helpful hint to identify a Flint block from a Tonawanda block. All FLINT blocks will have a small square headed plug between the front pad and the center of the block right above the timing cover. TONAWANDA block were cast without this plug with the exception of truck blocks. So this hint will narrow down your idenification but is not proof positive. Two additional ways to help identify the TONAWANDA block. The block will be cast with indented "T"s. The locations of these "T"s will vary. Also the casting date location on TONAWANDA Blocks varies. There are three common locations all on the rear of the block. 1. Right of center (passenger side) below the distributor mounting location (this is the same location as the Flint block). 2. left of center (drivers side) opposite of the normal location. 3. On top of the bottom most bellhousing bolt boss. this lettering will be at a right angle to normal lettering on the rear of the block. The Tonawanda casting date will always use the last two numbers of the year. Example 1963 will be A to K ??63.

      Your remote start will not work because your check engine light is on. Recommend you check for fault codes in the engine control module and antilock brake module.

      Sounds like fuel pump is out. Check fuel presure. Spec is 52 to 60

    Car is running very rough especially when idling at a stop. Acceleration seems uneven when starting from a stop
    IS this a fuel pump issue, fuel filter or something else?

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    Car is losing coolant as evident on garage floor. Repair shop has checked it and found nothing wrong. Any ideas?
    Car has 89,000 miles. Repair shop flushed coolant and replaced it--it has been 2 months since then and i have seen coolant on the newspaper that I had placed under the car at the engine area.

    Won't accelerate or change gears
    Previously the car will shut down saying reduced engine power and stall out randomly during the winter. The car bogs down when needing to accelerate quickly. Now won't even try to get over 20 mph. Checked the choke around the trouble body and it is covered in oil. ...
