Very new at this folks, but I need some help.

This is my second post of many to come as I am beginning my new project!

Here's my issue......... I just bought a Jeep in a near by city that has been sitting in a backyard for 22 years. It was complete and covered, but still needs everything. Here is the wierd thing, everywhere I look at information says that all 1947 Willys Jeeps had a 4 cylinder engine. Mine has a 6 cylinder (flathead) and looks like an original placement? You would suspect that someone simply changed it out, however, the title states that the number of cylinders is "6" also! What am I not understanding?

Thanks in advance for any help on this! Curtis
