What causes a 2000 Lincoln ls to run lean in both ports and still miss fire on cylinder 6 after complete tune up?
If it's misfiring AND running lean I'd suggest checking for a vacuum leak. Check the gasket between the manifold and the head, then check the EGR valve and make sure all of the vacuum lines are in good condition. Also verify that the power brake vacuum assist is in good condition and not leaking. A damaged power brake diaphragm can cause the engine to run quite lean.

How do you change over to HEI distributor from points?
It's a fairly simple procedure. The biggest thing you have to do is run a 10-12 gauge wire to the hot side of the coil in the distributor. The original small wire to your coil isn't heavy enough. Just make sure to wire to something that is hot only when the key is turned on. Other than that, run the vacuum advance of the HEI to a ported vacuum....not the manifold vacuum that the point style uses. Basically any vacuum port on the carb that is above the base plate.
