That's what their guy meant by "installed at TDC." Meaning no degree wheel, they rotate up to TDC and slam her home. Which is plenty enough to tell me I need to start at square one. As for the cam itself, I would go with a different grind but then I am looking at new springs since the stockers are marginal. All of that adds up and it's just not in the budget for now. If it moved a Ram truck, it'll move a 73 Charger.
