I have a 401 Nailhead out of a 65 Riviera along with its switch pitch TH400. The car had 98k on it when I pulled the motor and it had been sitting a while. It does turn freely and I would either rebuild it or at least freshen it up before I would run it. The trans also comes with the converter and cover. For anyone interested I also have eleven Holley 94's for a 6x2 manifold and a set of new Lake style headers with baffles for additional cost. I also have the correct, rebuilt AFB carb ready to run. Manifold - $SOLD Carbs (with a selection of jets and small parts) - $500 Headers - $350 Carb $200
