It is not uncommon for 426 hemiroids to suck oil into the cylinders from intake gasket leaks Do you own a leakdown meter and know how to do a leak down test? If so post the results. BTW,Andy DeFrank and Jim Cohen had a few different SS/AA 1968 Baracudas and Darts over the years Andy Defrank had more once they split up, I remember several different DeFrank SS/AA cars with that paint scheme at Pomona over the years, Rick Hauser drove a lot of them for Mr Defrank
