Description Compression Ratio Chart
 

Small Block Ford X Long Blocks are available in 408 or 427 cubic inch sizes. The D.S.S. Racing Extreme X series long blocks are geared more toward the serious street or sportsman racer who is needing the strength of an aftermarket 4 bolt block without the maintenance an all out competition style engine requires. Extreme X engines are strong enough to support high levels of horsepower but in most applications are very well suited for street / strip higher mileage cars. Extreme X engines are commonly used in high horsepower power adder 8, 9 and 10 second street able cars or severe duty road race / circle track applications. An engine like this is ideal for big boost and nitrous - do not forget that you have to have a strong enough engine to put up with your power adder. Having a top of the line power adder will only work if you match it with a engine of equal or better quality. We carry many varieties of high quality aluminum cylinder heads so please contact us if you don't see your favorite set listed here. The engine comes standard with a Ford Racing or a Trick Flow hydraulic roller camshaft although for most applications we will recommend a custom premium camshaft grind.
