430 c.i. 4bbl engine for sale. From our 1969 Electra Convertible. Car ran reliably for 300,000 miles when the engine was rebuilt, then ran for a further 15,000 miles until the car was junked because the frame was rusted beyond repair. We pulled the engine with the intention of using it in a boat project, but we never found marine exhaust manifolds to fit it. Plenty available for the nailhead and V6 engines, but nothing for the 430/455 big blocks. Anyhow, the engine now resides in a heated garage on an engine stand and has been oiled and turned monthly ever since. Located in west central Vermont near Lake George, NY. $1,200.
