Perfect cams for OE replacement and daily street-driven vehicles
These high-torque Comp Cams work very well on the street. Designed for engines with 9:1 or less compression ratio. They can be used in conjunction with most stock components, including intake manifolds, exhaust manifolds, carburetors and will not affect any vacuum or power accessories such as power brakes or steering. High Energy Cams will not affect air conditioning or your car's idle when the A/C is used. Normally, gas mileage will either remain the same or increase over a stock cam.Features:
Ideal for medium-sized engines (300-350 ci) that require good low-speed torque. This cam is a good all-around cam for family sedans and a great performance cam for turbocharged V6 and V8 engines. The 252H cam is a good replacement cam for OE that works with most stock valvetrain components. It also works with most overdrive transmissions and high gear ratios.
The perfect cam for vans, family sedans, pickups and tow vehicles. Provides exceptional power and a gas mileage increase, especially on the highway. With its great torque and throttle response, the 260H cam can also be used for OE replacement in most big block applications. Idle is smooth in large engines with stock exhaust systems. With headers, the 260H will produce a slight exhaust sound.
This is a very versatile cam. It is a great high-performance cam for small blocks and a powerful cam for big blocks. With its noticeable idle and great all-around power, the 268H cam is great for daily-driven performance vehicles. The 268H cam is an ideal cam for pickup drivers who want major power increases. It is also good for big blocks towing heavy loads equipped with lower optional rear end gears.
