Camshafts are ground to a certain firing order. Do you have any idea how a camshaft works? The camshaft can only work in one firing order (open the valve at the right time for one order of compression and combustion)
The 302 and 351 engines had different firing orders, and thus thier camshafts also had different designs.
The newer 5.0 HO engine uses the 351 firing order, but not the older 302.
