i need the ignition timing for 88 chevy 5.7 ... 350 motor i had the truck on 4 but still bad don t run good
your truck does not have a bypass connector
That year did not have a EST/ electronic spark timing connector. The timing is controlled by the PCM / Powertrain Controll Module. It requires a engine scanner to ajust the timing. You can not use a timing light.
18436572 same as all Chevy v-8s that is the firing order, not the ignition timing. timing varies between vehicles. a sticker under hood will give timing info, or a Haynes or Chilton service manual
Doesn't have a timing belt.
Chevy did not use timing belts on truck engines. T-chain only
can a chevy truck with a 350 engine with a tbi cause detonation and pre- ignition?
I did not get a answer
it has a timing chain NEUTZ
* Start the engine and run it at high idle until the coolant temperature reaches normal operation temperature on the dash gauge. Turn off the engine and disconnect the timing connector. The timing connector on the C and K series trucks is located on the passenger side of the firewall breaking out of the main wiring harness and is a single wire connector with a tan wire with a black stripe. * Connect the timing light to the battery. The red cable goes to the positive post, and the black cable goes to the negative post. Attach the timing pick-up to the number one spark plug wire. Number one is the front plug on the drivers side. Start the engine, and aim the light at the timing marks while pulling the trigger on the light. The timing on the 89 Chevy truck is 0 degrees with the timing connector disconnected. If the two timing marks you marked with white crayon do not line up, adjust the timing. * Set the timing by loosening the distributor slightly, and turning the distributor while observing the timing marks. When they line up, tighten the distributor. Turn off the engine and reconnect the timing connector, remove the timing light, and test drive to verify the repair.
