My 302 cam specs & rpm range

224 or 244 ? I thought in the other thread it said 224. I'm not a great cam guy, but if I had to guess it would be over 6k at 244.

What ever range it's got now with the stock heads, will move up with aftermarket ( better flowing ) heads. Here's one way to tell where it turns on now, just drive your car normally, easing on the gas gradually, at the point where the power starts to kick in, is where the actual rpm range starts, it will feel similar to when the secondaries on the carb kick in. The top of it is where the engine quits accellerating "pulling". It will still accellerate, but at a slower rate. On the 331 in my 89 Ranger, I can take off and actually "feel" when the engine's power curve kicks in, in this case it happens at 1500 rpms, it pulls hard up to around 6500, that's when I shift, it'll actually pull higher, but I don't want to stress the motor.
