Wow glad I found this thred. I have been planning on doing this EFI swap on my 440. Like the rest of you I have found out the dizzy is the hard part. If you have $700.00 laying around try this. http://www.massfloefi.com/replacement-add-on-parts/distributors/mallory-mopar-tfi-distributor.html If you are not made of money check out this link. http://www.gofastforless.com/ignition/tfi.htm Could it be true? Can you run a TFI unit on points? If you can a modification to the number one point cam lobe to shorten the dwell is all you would need. Lock up the advance and away you go. It may be too good to be true. Check it out and let me know if you think this will work. I have almost collected all of the parts to do this I just need a dizzy.
