“Buick Oddfire 225 engine. Early edition “Patent Pending” (the more desirable model) Offenhauser 360 dual port manifold, Kenne Bell valve train assembly with billet tip roller rocker arms and other high quality parts. I wanted to use this motor in a father / son project we are working on and my son wants to move in another direction. Engine is ready to be dropped in and put into service. First $550.00 cash takes it. I have an engine hoist here at the house to load into your pickup.
