Are you sure the Whipple Stage 2 your guy has is the Optional 700+ HP Stage 2 with the 68mm TB, 60 lbs. injectors and the 3.25 pulley?
No internals upgrading needed, but I advise the oil pump gear upgrade.
There are different options for the Whipple Stage 2 even all the way down two 650 HP Stage 2.
Yup, 3.25 pulley.
Neither one of these guys has done the oil pump gears, and they're in a hp race. I'm waiting to see which one pops first.
On a side note, I was looking in to doing a max effort naturally aspirated build with the 6.2 and was truly saddened by ford's engineering on the heads. It's pretty much a lost cause without a set of 4v heads... you can make 100 hp more with an ls3, at 100 pounds less weight, for significantly less money.
