True but the engines in this thread are 250-350 hp idle to 5500 rpm, So yes for you under 3000 rpm don't matter but for 99.98% it does and for most above 4000 rpm don't matter.
That's why I asked what I did in my first post. The bottom line is, match the cam to the combo and intended use, if you're building a truck engine, use a truck cam. If you're building something more performance oriented, use a performance cam.
Everyone that's fooled with these cars for very long has seen it over the years. Someone will show up with something that doesn't sound like much and outrun the guys with the dairy queen cams. Combo, combo, combo!
