Make sure the tack is not one of those 4-6-8 rpm selection models. If it is put the setting to 8cyls. I had a fiend claim he could do 9000rom with his engine until I heard the idle and checked the tack. I switched his 4-6-8 tach to V8 setting, then dared him to hit 9000. Never happened. -- Steve '63 Hemi Polara ---- Please address private mail -- mail of interest to only one person -- directly to that person.
