Glad to hear you straightened it out. Didn't a "Cam Card" come with the cam when you bought it?? It should have the correct firing order on it.

Vamp89,

You do know that there are two firing orders?? [15426378] and [13726548]. The later is the 351W/302HO firing order. The 302 went to the 321W firing order when the GT came back with a 351W marine cam in it. That is why you can't always go by what the intake manifold has on it. The cam dictates the firing order.
