Comp Cams Magnum Camshafts are very aggressive and specifically designed for the street enthusiast looking for more power with that Pro Street sound. Intended for performance oriented vehicles that will see little street use. The idle characteristics of your engine will change due to the increased duration and overlap of the Magnum Cam Series. You will notice a racey idle with the 280-grind while the 292 and 305-grinds will produce a rough or ''rumbly'' idle. Stock components are generally incompatible. Changes are needed in rear end gear ratios, headers and the torque converter. Magnum Cams will affect your power accessories to a certain extent. The 280 and 292-grinds are the biggest cams that should be used with power assisted brakes, air conditioning, etc. You should remember that the bigger the engine is, the less the cam will affect the vacuum which affects your power accessories. The smaller your engine is, the more the Magnum Camshaft will affect your power accessories. Most late model vehicles have a vacuum canister. If your vehicle does not have a vacuum canister, it may be necessary to add one.Features:Great high RPM power Easy on valve train parts Can be used with mild ratio rocker arms and traditional performance valve springs Best with aftermarket converter and 9.5:1+ compression
268H Series
Good street performance with stock converter, choppy idle.
270H Series
Great for high performance driving in street machines. The 270H has a rough idle in small blocks and a noticeable idle in big blocks. This is the largest cam that can be used with a stock torque converter. The 270H should not affect power accessories, but should be used with headers and 4bbl carburetor.
280H Series
Best for serious street machines. This cam has a definite rough idle and will sometimes affect power accessories. It can be driven extensively on the street or raced on the weekends. The 280H needs an aftermarket converter, intake manifold and headers.
286H Series
Designed to fill in the gap between teh 280H and 292H. For serious street machines and bracket racers. With a rough idle and lower vacuum signal, this is not an average street cam. At least a 2500-RPM converter must be used, but a 3000 is recommended.
292H Series
This cam is for the serious street/strip type car. An aftermarket torque converter should be used as well as headers, intake and increased compression. The 292H has a radical, rough idle.
305H Series
The 305H should really be considered for Pro-Street type cars where actual streetability is not a major concern. The design of this cam also makes it ideal for all bracket racing engines. Major engine modifications are needed as well as transmission and driveline improvements. The 305H works best in large cubic inch engines and has a radical idle. This is the only hydraulic cam in the series that does not have an advance made into it and will need to be degreed in.
