Where can you advertise used engine blocks for sale?

As of 2015, Automotix and Racing Junk are two websites that allow users to post used engine blocks for sale. After creating an account, users can post their basic listing for no cost.

On Automotix, the used engine block ads are listed with a description summarizing the brand, model and other key details, and usually includes a photo. On Racing Junk's website, they list the featured ads at the top of the page; registered account holders can pay $25 to have their ad included in this section. This site lists premier ads next, then shows a link for all other classified ads at the bottom of the engine block page.
