WebSep 23, 2024 · Check the dwell on an HEI module to confirm the circuit is evoking the longer (expanding) dwell time as the engine speed is increased. To do this, connect a tune-up tach and dwell meter to the "TACH" terminal on the distributor cap and then start the engine. At idle on a V-8, the dwell with a Delco module should be between 10 and 15 degrees. kaleigh croweWebHistory.
