This proves that the entire package is very important to consider when choosing the correct camshaft, and in most cases you'd be wise to consult an expert, not your buddies unless they're also cam experts, when selecting the perfect cam. As we learned in our tests, any cam can work well, but some cams can work better than others.
Separating the PowerLook closely at the two power curves for all cams. Note how the 106 and 110 lobes practically duplicate each other. Comp explained that since the engine we tested used a single-plane intake manifold and open headers, it breathed well and didn't need much help scavenging the cylinders. The 106 cam probably over-scavenged just a bit too much, and the 110 probably under-scavenged an equal amount, so the dyno pulls look almost identical.
Since the 108 lobe performed best, it showed that this engine liked only a little scavenging, and the 112 and 114 lobes' poor performance meant the this engine liked to breathe with a little bit more overlap to make the best power. The average and maximum power figures tell the biggest story. One true benefit to running a higher-lobe-separation cam is a better idle quality with more vacuum, so we listed vacuum at 1,000 rpm for each cam to compare. These results represent horsepower averaged from three consecutive dyno pulls with each cam.
