Hello all, I'm doing some research on the real world price for Zephyr v-12 engines. I have two that I am helping a friend sell and want to know what a good asking price would be. Both of the motors are completely rebuilt and in running condition. Thanks for your input. Here's what i've got: 1948 Zephyr v-12 with overdrive 1939 Zephyr v-12 3 speed I don't know much more at this point. Just looking for some friendly advice on what these might be worth. Thanks, JR
