Cute slip there on the subject! :) I'm trying to document my '7747 project on my web page--http://www.acesag.auburn.edu/~gparmer Given time, maybe we can even generate some kind of basic Delco FAQ. BTW--Steve...I've got Bruce's Delco Tuning Tips html-ized on the above site. Move that file to the the DIY_EFI site if you like. Corrections welcomed, -greg
