How can you tell what you got? Watch the tach and accellerate! If you have the typical "low rpm" cam you CLEARLY run out of "power" at about 5200-5300 rpm. That would indicate your max H.P. rpm would be around 4500 rpm.

Ford Motorsports offers TWO cam that are petty typical applications for a 302. One is the "torque" or low rpm application, the most common one used. Tops out around 4500 rpm, pulls strong from as low as 1500 rpm.

The other "typical" Ford Motorsports cam is the High rpm version. Comes on around 4000 and pulls to about 6000.

Basically, accellerate and try to note when it seems like the "power" is falling off. Just BEFORE that happens is a good "red line".
