great build 1000+rwhp shouldnt be a problem for sure.
WHat transmission do you have??
I think the 3.42 wont be enough with that power in the texas-mile.
Keep us posted please with vids and numbers.

Will have to see. I expect to shift out of 4th at 155-158, that puts me at 5,000 in 5th. Will have to see how strong the engine is to pull 5th. 210mph is the goal.

I'm curious why the need for the maf card? Most boosted set ups go with a speed density tune, I'm missing something here?

SD on new cars isnt so easy like the 04 and older cars.... Old cars= slow processors, so SD was the way. New cars=fast processors, MAF is the way 
Card maf in a 4" tube is good for 800 on a blower car. Smaller tube=less HP before its maxed out. 75mm MAF= maxed out at 500 
Good luck John!!

It's always something. The LS2 intake bolts do not work on LS7 intakes and the 3/8 pushrods rubbed the heads, so we had to order 5/16. Hopefully it will run next week.
What length pushrods? I have most common ETP lengths on the shelf, and lots of LS7 mani bolts. Thats common, LS2s are long, LS7s are short.

I have not had the car in 7 months. One more week won't kill me.
