Cams for Dummies ??

And something to remember. Most cams will make an engine run. Many will make it run better than the stock cam that's in it. Some will make it run better without changing everything in the power train to make it work. See where I'm going here? Unless you are class racing and need that last 10 horsepower to be more competitive, choosing that "perfect cam" isn't all that important. The differences in a half dozen cams will show up on a dyno sheet but you may not notice much difference at all in the seat of your pants or from stop light to stoplight. Like I mentioned in my previous post but I'll say it again a little differently, Don't go too big unless you have the rest of the combination to make it work. (or you are willing to make those changes)
A little common sense goes a long way here.
