When to set initial timing on Summit HEI distributor?

When to set initial timing on Summit HEI distributor?

We prefer to set the initial timing for most engines at 10 degrees Before Top Dead Center (BTDC). With that set, remove the cap from the distributor. We’re using a Summit HEI distributor.

Where are the timing marks on a front wheel drive car?

Some engines in front-wheel drive vehicles have timing marks on the flywheel. A pointer is attached to the timing cover. When the mark is exactly under the pointer, the engine is ready to fire number one cylinder. The spark will occur with the rotor pointing to the number one cap terminal.

How can I tell if my timing chain has slipped?

Listen for any abnormal engine noises, with the engine idling, in the vicinity of the timing chain cover. Chains that have slipped time have slackened and can sometimes rattle during cold start or idle, or produce a swishing or scraping noise.

How to install a distributor and set initial timing?

Leave a little extra room with the spark plug wires to allow freedom of movement in the distributor. For Chevys, be careful to make sure 5 and 7 are installed correctly. If the wires are accidentally switched, the engine will not be happy. Before we try to start the engine, be sure the distributor is connected to switched power.

How does a GM HEI distributor work on a car?

The GM HEI distributor uses a hall effect for the triggering and sensing the No.1 cylinder location and the rpm of the engine. It uses an ignition module within the distributor to regulate the timing curve as well. It will automatically advance the timing on acceleration a specific amount and retard the spark when decelerating and starting.

Where is the plug wire on a HEI distributor?

Here’s a few tips: Number 1 plug wire should be at the front of the distributor just to the driver’s side of centerline. If that’s not your #1 plug wire then you have the distributor installed off by a few teeth. It won’t hurt performance if timing is still set correctly but plug wire routing gets a bit messy.

Can a GM HEI ignition coil be replaced?

The GM HEI distributor’s springs can be replaced with three different weights of springs that, in effect, allow the advance at lower rpm. The ignition coil is housed in the distributor cap, which makes the GM HEI distributor a very efficient, self-contained unit.

How can I tell if my HEI distributor is still running?

Check the coil tower for excessive wear. Remove the top plastic cap on the distributor cap. Use an ohmmeter and check the coil positive terminal to the metal case of the coil. The reading should be infinity. Check the coil tower and the negative terminal. The reading should be 900 ohms. Check the positive terminal to the negative terminal.
