1-8-4-3-6-5-7-2 is a very common firing order for older V8s. If you have a Chevyor a Dodge V8, it's probably a lock that this is your firing order.
Firing order is not by any means a criterion for engine ID. There are two things that you can look for that will identify your engine:
1. Casting number. Look for a 7-digit number that is cast into the block. This is not necessarily a positive ID, but it narrows down the possibilities. It's often located at the rear of the engine block , behind the head mounting surface.
2. Engine serial number. It will usually be stamped, as opposed to cast, on a machined surface in the front of the engine. This number will give you specifics about your engine, and is the best way to ID the engine without disassembling it.
