I have a one owner 69 Sprint and I can tell you that if you are going to restore and need engine parts you best get to looking for them now. Also, the "H" cam in that engine is not reproduced at this moment so take care of your motor. I am working on getting someone to reproduce camshaft from a blank mold so we can get all of the factory grinds. I would suggest that you go to the Yuku OHC forum and looking for this thread so you can participate.
