All of our complete engines carry our industry leading 3yr/unlimited mile no hassle warranty. If you ever have a problem or concern with your combination, give us a call and you will be taken care of.

We are located in the small town of Boerne TX, about 10 miles northwest of San Antonio. All of our operations are based out of our facility in Boerne. We do not outsource any machine work and every complete engine is dyno tested in house with our state of the art Superflow Dynometer.

Absolutely! At Smeding Performance we believe in unbeatable quality, period. That is why every single part used in a Smeding Performance crate engine is 100% brand new, nothing is reused.

We recommend Driven Hot Rod 10w-40 conventional oil in our SBC, BBC & SBF crate engines, and Valvoline VR1 10w-30 or 20w-50 oil in our LS combinations. Every current Smeding Performance crate engine uses a high performance roller camshaft, and adding extra zinc additives is not required when using the oils listed above.

Even though synthetic oil does offer advantages such as a wider temperature operating range, the composite fiber gaskets used in these "classic" engines were never designed with synthetic oil in mind. That being said, our LS line of engines and their o-ring gaskets can take full advantage of the benefits synthetic oil has to offer.
