In pro-stock you better find every hundredth and thousands you can, if you don't you probably won't get in the field. Ron Miller, Greg Moser and I discovered this long ago. Greg was always calculating transmission ratio's to go faster and quicker. With a bunch of scribbling on paper and gear sets laying all over the place I decided that their has to be an easier way. The winter of 1997 I came up with this program for our team and we have been using it ever since. Ask most any IHRA Pro-Stock team, they will tell you that this program is a must to have.
