The S&S Street Pro engine was first introduced as part of the Tribute 145 finale in August of 2003 at the Broken Spoke Saloon in Sturgis, SD. A Street Pro bike built by S&S, G2 Motorsports and Gail's Harley-Davidson® was a result of George Smith's desire to build a big bore competition engine for 1999-up big twins and Brett Smith's desire to pay tribute to S&S Cycle's racings roots.
S&S and Star Racing offer a number of engine packages designed for competition in the AHDRA Street Pro Class ranging from 120" to 139" (the 120" is also AHDRA Pro Mod legal). All S&S Street Pro engines are 45° V-twins, built with the S&S TCSA crankcases including the S&S gear drive cams.
The S&S Street Pro Engines are available with rear motor mounts for either 1984-'99 chassis or for 1999-up chassis. Engines with the 1999-up style rear motor mount are intended for use with Harley-Davidson® transmission for 1999-up. Engines with the 1984-'99 style rear motor mount can be installed in any 1984-'99 style frame, providing the frame will accommodate the taller heads and Pro Stock style exhaust location.
