Here is my cam -- it's an old school cam that has a wonderful sound and idle when tuned perfectly along with decent manners down low. Remember is a solid flat tappet. Now jhv48's comments on the RPM drop are valid. Unless you're really sure how you're going to drive the car, the .81 ratio is the safer choice. But you should ask your builder what's the lowest sweet spot in your rpm curve just so you can do your math. Remember though, regardless of what you choose it will be better than an original Cobra with a four speed.
