I have had it since the early 80's. I pick up a couple went they were plentiful. got a lot of a body part that I need to thin out. more then I will use for my projects.
I started to clean out garage and sell some of the thing I have save all this years. Just checking what this may be worth. 1970 340, J heads with 202 valves ,was pulled out of a wrecked car, tore down greased up and put in storage over thirty years ago.
