The "CAM003" cam has been produced by Mini Mania for well over 20 years and has been used extensively in our 1380cc engines becoming legendary in its own right. It is the ideal road cam for 1275cc or 1380cc, below 5500 rpm the CAM003 produces more power than the 286 profile. The average driver spends 90% of his use of the car below 5,500rpm. Our 'Second Generation' '003' grind is now called "CAM103". Not only does this produce over 115HP in our 1380cc motor but it is even more streetable, pulling strong from as low as 2,000 upto 6,500 with ease. All of this with stock ratio rockers and single 1 3/4" carb. One of the added features of the "CAM103" grind is the great performance in small bore applications such as 998 and 1098cc engines. Not known for their high rev potential this second generation cam provides all the bottom end you will ever need but still helos transforms the motor into a hot street version.
Not for use with Fuel Injected motors (MPI).

Camshaft selection can be as complicated as you like, but for the ultimate performance, even if that means best gas mileage requires that you consider the entire envelope that the camshaft will work within. Non-technical issues such as intended application (street, race, milage or??), budget, expected RPM range, etc must be considered along with technical things like compression ratio, Cylinder head and valve sizes, exhaust system, carburetion, etc.
Camshaft Theory by Elgin

Considerable information has been recorded about numerous aspects of the four stroke internal combustion engine. Nevertheless, only a small percentage of people really understand how it works and even fewer still know how to modify an engine to suit their needs. I will try to simplify this complex subject by discussing some basic principles that may be overlooked or misunderstood by the average person. First, it is very important to understand the relationship between piston travel directions and valve timing events. The reason this relationship is important is because it is one of the few things that is relatively easy to adjust/change. The camshaft which opens and closes the valves makes ONE complete revolution (360 degrees) while the crankshaft moving the piston up and down the cylinder rotates TWICE (720 degrees). Camshaft timing is usually expressed in terms of crankshaft degrees relative to the piston location in the cylinder. That is, relative to Top Dead Center (TDC) and Bottom Dead Center (BDC), respectively. Note that during the four strokes of a piston in an internal combustion engine the crankshaft will rotate 720 degrees and the piston will be at each TDC and BDC twice.
