As far as I know, the S&S T143 Long Block is the largest S&S engine that will fit in a stock Harley- Davidson chassis. If you’re the sort of person that thinks the quadruple bypass burger at Heart Attack Grill is a good appetizer, this might be the motor for you.
While it lacks cheese and bacon, the motor does have 143 cubic inches of displacement. With a reported double the ponies of a stock motor, this isn’t your typical crate motor you can just slam into a frame for all-day cruising. The power of the T143 requires technical expertise for the installation and tuning, along with an experienced rider who can pilot something this powerful. To give you more info on the T143, check out this video from S&S themselves.
This is an ultra performance/ race engine. Longevity, engine noise, vibration and throttle sensitivity have all been compromised to reach this level of performance while fitting in a stock chassis and as such is not suitable for every situation. Meaning, if you buy one, it’s on you to decide if the T143 is suitable for your project.

What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George J. Smith had to build his own parts to make his motorcycle faster. Now the company he founded manufactures the most pretigious line of "go fast" v-twin engine parts in the world. The company was started in the basement of his home in Blue Island IL in 1958, and moved to Viola, WI in 1969. In 2004 an additional facility was opened in La Crosse, WI.
