In my quest for parts I came across what I think is an early 3A but with an Fhead engine. The owner told me he put this in when the L head was getting tired and he found this one rebuilt. Is there any value to this engine? It started right up and did not smoke but other than what the owner said that is all I know. I could buy the whole thing and sell the F head to the later Jeep guys but dont relly know what a running F head is worth.
