Another "Is Fuel Injection a Worthwhile Upgrade?" Question

Thank You so much, AndyF. I'm liking you information like you wouldn't believe. My Swinger 340 has a great condition, original harness, including the 40 amp or so alternator. I know this needs to be upgraded. If a new harness needs to be installed and modified for this system, I'm capable of buying one, and modifying it to make it work with an EFI system. I believe I'm going this way. I believe I can make a high performance EFI system with your help, and keep my RPM Airgap/QF750 as a backup. For ignition, I'll ask all members for their advice. I have an MSD E-Curve I picked up tears ago, NIB. Is this outdated? I've been collecting parts for 15 years, and I realize technology has marched on. I can sell these parts without any heartburn to members here. I think I should spend my money on the new TF single plane manifold to match the heads. Please, all members, chime in.
