Default Re: Which Cam

Those charts are for reference only. You actually have to measure the chambers to determine the CR. In my book I measured a dozen or so heads and they were all over the place. Another consideration is the difference between Static and Dynamic compression. This is determined by the closing of the intake valve. An L-100 cam drops an 8: 1 CR to around 6:1. Good reason to have more cubes.
