1995 350 ci 250 hp with EI. My problem is when I adjust my distributor the timing mark does not change. I am not sure of the model type of EI, but there are 2 wire connection harness bolted to the distributor. Would this be a thunderbolt V ignition. If so I have read the topic: Base timing on Thunderbolt V ignition. I was told I need the bring my timing back to base time. This all started after I rebuilded my cylinder heads, and now I'm try to set my timing.<br /><br />farley
