A built 351w with plenty of speed parts could easily double the factory horsepower that came with that car. That would be a fun build. Swapping in a big block would be a lot more work.The picture of the engine is too dark, but it should have the 351w since it has a VIN 2. Not a high output beast, really hobbled with emissions restrictions. The 400 was better, but not by a ton in the cars.
