I am trying to find information on a Chrysler Industrial Flathead 8 Cylinder Engine Serial #36-6421-IND9-67M, Model #8881 with a Gorman Rupp water pump Serial #143298, Model #55M. I have looked all over for information on this, but can't seem to find anything. Anybody have an idea of what the value of something like this would be? Any help would be really appreciated. Thanks.
