I agree. I wouldn't be surprised if there is 2 tenths or more left in the car. I'm working on that as well. Double adjusts for the front as a start. Next time I go to the track the car will be in race trim. I guess a 10.20 is the new goal and a tunnel ram will happen regardless of results. There is another example, my 408 with 4" stroke and 4" bore ran a best of 10.38@131 mph. This 511 with 4.25 stroke ran a best of 10.40@129.75. So more cubic inches are not always a win win and I have seen a few of Millers w8 motors put a big block to shame.
