Some people on the top 10 list have run such a large cam that flycutting the pistons were needed. But for my cam choice flycutting is not needed. The current record is 10.219@132.29 through a m6 that was set back in march of 2006. Back in December I tripped the beams in my car and trapped 131 at something like 14 seconds lol The day my motor blew up I ran 10.35@127 so the potential is there. FWIW my old motor probably had 30 dyno pulls and 60 passes on it spinning to 7200 rpms.

So you could blueprint the pooh out of the stock short block and the components, you just can't swap them out for lighter/stronger parts? What about overbore? Just a hone and re-ring or is some small amount of overbore permitted?
Color looks good, even though I don't car too much for blue, that shade looks good against the black top. Nice.
