It's about time! I shouldn't have sold my HPT Pro to you Victor. Now I have to buy it all over again so I can swap tunes back and forth as well.
I really did intend to keep my warranty good when I first bought the C6. Oh well, I'm too impatient I guess.
I'm also eyeballing those RPM small bore LS7 heads. What are you doing with your old stock manifold, fuel rails, and injectors?

by the way... i was informed by many people (jason included) you shouldnt mill the heads if going with the torquer cam unless youre running e85. the DCR on the cam is 9.1 without milling and would be too much with milling on 93 oct.

dont know how thatd work with 91 unless you always run a mix of the two?

I'm switching to E85 as my primary fuel. I will hav my 91 pump gas tune for whenever I travel with the car and don't have an E85 station handy. WE can tune the car for operation on 91 to get me out of a bind, but you certainly wouldn't want to beat on it with only 91. If I so chose to do so, I could run meth with 91 pump gas and be fine as well.

Yep, I've researched my config for almost 2 years.
You could use pump gas and meth to achieve the same thing, from an octane point of view, but I also want the cooler engine temps that come from running E85, and the usual bump in mid range torque that E85 offers.

Looking at how the planned mod list goes, this almost looks like a Katech Stage 2 Z06 but not done by Katech.

I had a similar plan when I did mine.

I believe they use SS or Inconel on some of their FI builds, but you are right regarding N/A builds.

Yep, exactly what I'm doing......very observant, Quick !!!
On top of that package, I added a NW102TB, a .030 mill, 60# injectors, and E85 . I've built myself a psuedo Katech Street Attack C6 Z06

SS on their value LS3 based 427 long block and 454LSX
Hot Rod motor, Iconel on the LS7 TT motor.

All other builds, including the Air Attack LS7 SC with the Whipple 2.9 pd blower or Procharger D1, uses hollow sodium two piece

Katech does use inconel valves for the their TT Air Attack package. They maintain the 7000 rpm redline with a custom cam profile for that package.
