Thanks. The print is a bit light, am I reading this correctly, I 28/64 E 66/30? How did the cam work out for you. How much did you gain and what was the previous cam?

Those #'s are correct. I've had good luck with this cam, easy on parts and car runs consistent. I really don't have anything to compare it to, I changed the combo when I installed it. In stock stroke 440 we advanced to 102 to run 10.30's in current 4.15 stroke we put in at 106, I race on a 10.50 index so plenty of power for me. I run an A&A factory crossram so probably leaving 75hp over a single plane and dominator. Been best of 10.16 @131.
