So I found your build thread while looking for drag wheel/tire setups, ended up reading every page. I started first by thinking "Hell yeah he's already done everything I'm currently in the middle of!" Which then quickly turned in to "Noooo! He's doing everything I told myself I wouldn't!!"
Excellent to say the least. I'm in the middle of, what I told myself would be, a mild NA build on my 08' short body Denali. Front/rear 4.11s, Circle D 3200-3400, TSP 229/244 ls3 cam and vvt delete(thankfully being an '08 the AFM hardware wasn't even present), plus the usual LS valvetrain uprades except I'm reusing stock valves. That was all phase one of the build. Phase two entailed cnc ported stock heads, manifold swap, and flex fuel conversion. Two of the new lifters failed right off the bat so instead of pulling the heads to replace them, and then a third time for phase two, I just expedited phase two and am doing it all at once.
PS, your LSXcalade counter part is the welder at the shop doing the work. I just don't have the free time or space to do it at the house.
As you can see from the post count, I'm more of a reader, I was active as hell on the cobalt forums. I felt the need to post though and just say, badass man.
