So, I've been thinking about getting a new HEI distributor for my V8 '81 MC . It's nearing 200k miles and to the best of my knowledge still running the original distributor. It is an ECM controlled unit. All the replacements I've seen from parts store are versions with the vacuum canisters. Rebuild kits come with vacuum canister as well. My car is stock regarding the ECM, HEI, wiring, sensors, etc.
How should I go about with this upgrade? Is it possible go with one of these new units, remove the vacuum canister and somehow add & modify the ECM wiring harness from the car to the new unit? Can I use the new unit as is, tap into a vacuum port, leave the ECM plug dangling Should I rebuild my existing distributor with a kit, minus the vacuum canister?
I'm trying not to cause a check engine light or other misfire by leaving the ECM plug just dangling there.
Thanks in advance.
