Hello,
I am repairing my 91 GTA L98 350. I want to replace the stock ECM with a FAST XFI, Acell DFI or AEM ECU. FAST XFI system seems to be the easiest. Anyway, I intend to create a coil per cylinder, distributorless crank triggered ignition system.
I need to eliminate the stock distributor as my new custom manifolds and plenum will not allow it.
Correct me if I am wrong PLEASE.
I believe the HEI distributor preforms three functions other than spark distribition:
1. Provides the Tachometer signal ???
2. Drives the oil pump ???
3. Hole in distributor shaft lubricates the rear of the camshaft ???

Problem: If I eliminate the stock HEI Distributor;
1. How do I generate a signal to run the Tachometer ?
2. How do I lubricate the engine properly at any RPM ?
3. Not sure how necessary this is since no distributor gear to lubricate.
