1/4 mile times on average would probably favor the S1X unless you go for at least 3.29's and a stall. Car barely gets into 3rd with 2.93's at the 1/4, so you really want to capitalize the low and mid-range. One of the reasons I came up with my back half MPH list was to help me decide on what cam phasing I was going to use. The results brought me to the conclusion the car needed more grunt in the 3000-4500rpm range, so advancing either cam would be a good idea if clearances are checked properly.
Remember, if using the Rollmaster, it was developed for the L36, so it may be retarded 2 degrees when installed straight up in an L67.
