An old Motors Manual from the late 60s will show the flow for the 290-390, which will be the same as the 401. Before cars became land locked space capsules Motors actually showed how to fix things. You can pick up an old Motors manual at a swap meet, wrecking yard or library....Russ __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
