Excellent Chase! A very much misunderstood component, and far to many are NOT matched to the build or the goals of the customer. The 2 biggest subjects I see misinformation on are:

1. NA cam that is also best for FI. No such cam grind exist's.....all will run, but the type FI requires the proper profile to optimize power, and:

2. "I want a lopey/lumpy idle" This we battled for ages with carburated big cam builds.....this is why we have to idle the drag engines at 1000-1200 RPM to get a signal to the carb. This may sound cool, but it is not the most efficient or optimized for power...expecially off idle. Comp introduced their "Thumper" line due to demand for the sound, not optimal performance.
