A Top Fuel engine block is a special piece of engineering.

Starting from a gigantic billet of aluminum, an engine block will be machined, but this is no ordinary block, this one belongs to an NHRA Top Fuel dragster.

The machining process begins on a five axis milling machine, capable of positioning the material in any required direction and place. Roughing tools give the piece its general shape, and then, finishing tools get the surfaces looking shiny. The block is then sleeved and prepared for assembly.

Chasing performance in the Top Fuel category requires equal amounts of passion and technical expertise.
