Is there a simple/easy way to ID a 273 engine vs 318?

Is that really the most distinctive difference between the two? (I already know the answer, but I have to ask)

Yes it is the most distinctive feature. My post 16 has photos of the two distinctly different valve covers.


They are different engines. There might be internal parts that are interchangable?

But it's easy to tell a poly from an LA by the valve covers.
