Is there a difference between the 318 and 340 caps in the locating width (for the channel)?

No, they locate the same, and are completely interchangeable as long as you use the correct length bolts.[/QUOTE]

I wonder if they built them on the same assy line at Mound Road, or on different lines...

They used to build the 3.9 L and 5.2 L on the same assy line in the late 90's. The 360's were made in Mexico then....
