Thank You all for the welcome. I drive an '85 F250 4x4 4 speed manual and have recently discovered it has a 351W with a very screwy ignition system. I am planning to find me a 94 or newer 5.8 to rebuild and equip it with a DS II distributor and module with the blue grommet where the wires come out of the module. I apologize for taking so long to post here, I had to have double bypass surgery on the 21st so I have been a little under the weather LOL. I appreciate all the advice I can get and will be glad to share what little I know.
