With you, the serious racer in mind, we have designed and machined the ultimate engine case. The case is cast of 356-T6 aluminum. The castings are flawless, with zero porosity, which makes the strongest possible part. Prototype cases were X-rayed from six sides by an independent lab and received an aircraft spec.

Some of the outstanding features include:

• Four parts: two case halves, a front cover and a rear engine plate
• Case halves located with six hardened and ground dowel pins
• Two oil scavenge pick-ups

• Lower bolt-in windage tray
• Machined for a future internal rev-kit

• Ready for either a two stage or three stage dry or wet sump system

• Front cover can be easily removed for access to the camshaft gear
• Ability to change your cam timing without splitting the case halves
• Front cover has two hold down holes for the magneto mount
• Rear engine plate is doweled for location
• Rear engine plate is fastened with nine allen head cap screws
