Post vaccuum line eliminations

Let me explain what I did first so you will know where I am.

On my 1983 Chev full size truck w/305 (not a cal engine) installed a 350T trans, I pulled every vaccuum hose (eliminated) except for the PVC, Trans Modulator, break vac assist, Vac advanced, Tip-Off vac switch (more on this later) I pulled the EGR and capped the manifold with a EGR block, also eliminated the Fuel vapor canister.

I pulled the OEM Rochester quad and replaced it with the Eidelbrock 650cfm manual choke.

Ok, the question is; would there be a problem keeping the OEM Electronic Control Module (ECM) or should I replace with a after market? Any reason to keep the Electronic Spark Control sensor (ESC) and the Tip-Off vac switch connected. (The distributor is HEI)

As it is now, the truck runs excellent. Just wondering with the mods I made, I am wanting to eliminate everything that doesn’t need to be connected!

Later on, Feb or Mar I am installing an Eidelbrock Intake-Manifold and RV Cam kit (basically for slight top-end improvement, NOT looking to race it)

Any thoughts or suggestions?
