Everybody knows that S&S engines make a lot of power. What you may not be aware of is that because of our innovative designs and premium materials, they last a lot longer than you might think was possible for a high performance engine. Let‘s face it, the stroker engines of the late 1960‘s and early 1970‘s were pretty crude by today’s standards, and they gave high performance motors a bad reputation as far as engine life is concerned. But keep in mind that the high performance industry has come a long way in the last 50 years or so, and S&S has been a leader in the quest not only for more power, but also for greater dependability and improved engine life. So if you could double your horsepower and still get near stock engine life, wouldn’t that be a fair trade off? Judging from the number of large displacement S&S engines on the street, the answer seems to be „Yes!“.
Buying an assembled engine from S&S is the surest way to get S&S quality from start to finish. S&S parts and S&S expert assembly! But how do you know for sure that the engine you have was really assembled by S&S, and how do you know that all the parts in it are S&S? The answer is simple. All complete engines assembled by S&S in Viola, WI, USA come with a certificate of authenticity (see picture) that let‘s you and your customer know that they have the real deal. Buyer beware of any engine that does not come with a certificate of authenticity!
