Run the same engines we used to win multiple road racing events and a National Championship! These shortblocks are fully machined before being professionally assembled with UCS Performance Spec parts. Forged rods and pistons are included along with race series bearings. The balance shaft bearnings have been removed or turned allowing for the use of a balance shaft elimination kit. These shortblocks have been proven to handle over 700awhp on a Mustang Dyno with the appropriate supporting modifications.
