What else can I do to the LS7 without going pour
I have
catless longtubes
x pipe
cam (specs below)
duration at .050 intake 240 exhaust 248
lobe lift intake .3430 exhaust .3400
gross valve lift intake .617 exhaust .612)
titanium valve springs/retainers
mahle forged pistons
ferrea exhaust valves
CR 12:2:1
and I just added a ported FAST102 and Nick Williams TB.
What else can I do without cracking the motor open? My CR is pretty high so I doubt I'd be able to boost.
Am I at the high $ little HP stage?

I am not sure what you mean by cracking the motor open since you already changed the cam and pistons but I would suggest some CNC ported stock heads. I have seen some nice gains with LS7 heads ported by LPE, Texas speed, SDPC and it is relatively inexpensive.

I'd like to stay N/A plus I'd primarily be using this as a street car. I'd be too tempted to use the juice on the street in those "just in case" scenarios
on a full bolt on LS7 with upped compression how much would I gain from ported heads?

Try this ,the cam duration is pretty good add more lift say around 640-650 lift and have the heads ported by Frankinstin or Darwin@ Reher-Morrison...you can get 600rwhp = 680-700fwhp call Ron @vengence 600rwhp is done there all the time with the ls7 N/A.

Yeah I'm thinking possibly heads are the last step here pretty much. How difficult is a head swap on these cars? I did it on my old HEMI 6.1 but not an LS7
larger meaning from the X pipe rearward?

There's not too much I'd change if I were you. With out adding some sort of power adder, the only thing worth looking into IMO is, having the heads ported by either Frankenstein or Reher-Morrison and getting better valve events spec'd to take advantage of the additional flow.

well i copied John B . just with a lq9. Just heads and cam but have the intake gutted heads flow over 400cfm intake is limited 2 around 340 -350cfm gutted thats a fast 4 u. But really,a good port job and the right cam. John's ls7 is my pick of any on this site it is a simple 427 good parts and let that ***** F¥€«»ER BREATHE.
