The Wildcat Billet Side Covers differ from the regular Tillotson/Clone/Ducar and Predator Hemi with an additional bolt hole in the bottom of the side cover like the stock Wildcat side cover. The additional bolt increases the clamping force and reduces flex and distortion.
The EC Billet Side Cover contains many new features not found on many billet side covers on the market.
We utilize our latest PCV(Pressure Control Valve) design for controlling crankcase pressure and venting. There is also a second fitting for additional venting or to be used as a vacuum port.
One of the most significant advantages is our oil sump capacity. Another often overlooked benefit is our oil fill channel allows smoother and quicker oil changes. Less time wasted waiting for the oil to drain into the engine. Unlike many billet side covers on the market, we maintain the original engine oil capacity. Other Billet side covers reduce the engine's oil capacity by making the side cover flat on its inside.
What does this mean, and why is it an advantage? Easy, Your oil should contain an additive package suited to your engine, allowing better performance and protection, including friction reducers and wear inhibitors, among many other properties. These additives do a better job when more additives are available, especially when the heat starts to break down the oil. Your oil also works as a heat sink to cool the engine. More oil takes longer to heat, meaning a cooler-running engine and less oil breakdown over time. Again the more oil you can run and keep in the engine, the better.
The EC Billet Side Cover also has a machined groove around the perimeter, allowing better crankcase sealing with an O-ring. We stabilize the side cover using two solid pins to replace the hollow stock pins and secure it with 8Mx35 cap screws or upgrade your hardware with our EC Stud Kit. For the most strength, we recommend using Tillotson reinforced blocks. We designed the New Tillotson blocks as the ultimate track weapon when using our new EC Products.
Our attention to detail, high-quality machining, and innovation are what you have come to expect from EC Carburetors.

Warning: This side cover will not clear engines that use stock fuel tanks mounted to the engine. This side cover is designed for racing applications only. The side cover has no dipstick due to racing engines changing the oil frequently during race events.
