ramblinon9 Posted August 17, 2009 Share Posted August 17, 2009 Hi there my name is Christian and I recently purchased a 73 with an 83 l28et in it. I bought it basically not running and I've gotten it to the point where it runs pretty good now. Now that I've gotten it running decent I started looking at some of the things that I want to take care of, and one of the first things I came across is that it has a na dizzy in it. I'm not sure why? or whats going on with it because the advance port on the side of it is blocked off with some sort of epoxy. So my question is why is there an na dizzy running my l28et? Thanks a lot. Quote Link to comment Share on other sites More sharing options...
ktm Posted August 17, 2009 Share Posted August 17, 2009 So my question is why is there an na dizzy running my l28et? Obvious answer, because whoever performed the engine swap used an N/A dizzy. What is your real question? Quote Link to comment Share on other sites More sharing options...
ramblinon9 Posted August 17, 2009 Author Share Posted August 17, 2009 are there any problems that could ensue because of this? and why is the advance port blocked off? Quote Link to comment Share on other sites More sharing options...
smokeybear Posted August 18, 2009 Share Posted August 18, 2009 Someone correct me if I am wrong but I think it may also be a locked dizzy so it doesn't pull a bunch of advance timing. I may be totally wrong there but I think that is why. Quote Link to comment Share on other sites More sharing options...

I may be totally wrong there but I think that is why. Correct. As NA and turbo motors require different ignition curves, in order to keep an NA dizzy for a turbo swap the mechanical advance needs to be locked.
