The early Donovan aluminum big block Chevy (BBC) engine block was previously built as a 540ci ProCharged engine and is being sold as a project. It has never been windowed or welded and appears untouched in those areas. My current engine builder believes it would make an excellent naturally aspirated street or bracket motor rather than a high-horsepower boosted combination, which is reflected in the price. I also have the GRP aluminum connecting rods, matching pistons (approximately 70 runs), 904 lifters, camshaft, Titan 10-quart dragster oil pan, and Titan oil pump from this engine available. The Titan oil pan and pump are $1,000 OBO, and I’m willing to sell the block by itself, the oil system separately, or everything together as a package for $3500. Feel free to reach out with any questions or to request additional photos.
