¥ For serious power in 88 cu. in. and up, 10.5:1 compression, head work, performance exhaust and carb VThunder¨ cams provide the ultimate in arm-stretching, white knuckle power in both street and competitive applications.

Most cam designers concentrate on getting the most power in a particular RPM range and disregard valve train clatter and power band width. The designers at VThunder¨ pay particular attention to ramp design to keep our cams as quiet as possible and lobe design to maintain as wide a power band as possible. VThunder¨ cams are made from 6150 aircraft quality steel for ultimate durability and resistance to premature cam failure from metal fatigue. We heat treat our cams to provide a case depth that allows for long term use under extreme loads. With the aid of computer controlled machining centers, VThunder¨ cams are held to extremely precise tolerances.
