You don't need juice to make it go. Just hook up the throttle direct and remove govn. on it. It will then spin to 6200 rpm safely if it is the Tec. OHV engine. :nod: But will only reach about 5200 due to the gearing it has.
Add a header and high-rev valve springs and you are good for 7500. If you want 10,000+ you will need a billet block and full internals.
