Default Cam Question for Turbo

I’m looking at 3 different cams at the moment... the 06 Z06, Lingenfelter GT-7or the LS9 Supercharger cam. What one would you pick for my goals and am I missing anything extra that is needed to make that cam work in the LS1
06 Z06 - direct drop in?
Lingenfelter GT-7 – direct drop in?
LS9 Supercharger - 2005 LS2 front cover, 2005 1x cam sprocket, camshaft extension harness, 2005 LS2 chain damper (is this cam worth all the extra cost)

I’m going to running a turbo setup from josh @ KT, LS1 with a forged bottom end and 317 heads, 60lb injectors, and dual pumps. My goal is 700~750hp.
I don’t know much about any of this so id like to get some help.

The lingenfelter cam would be the only direct fit. As the other too would require Ls2 front cover and are also single bolt cams.

I think there are other cams out there that would be better suited for a turbo set up

I ran the gt7 no problems and as said its drop in. I have ls9 in my current ls3 based ERL .I did as said have to go to ls2 conversion kit.The gt7 worked great in my 408 no complaints,easy to tune, no low speed surge. I hate low speed surge.Not too high on lift but bumped it up with some 1.8 YT rockers. This time around went to ls9 with 1.7 YT rockers a bit mellower on the lift. I am close to having the car running but expect the ls9 cam to be very mellow and easy to tune as well. I don't like radical cams with my turbos.I will have way more power than can ever use and so prefer a very civil but boost friendly cam. Don't like lope in my 99. Thats fine in an old chevelle BBC.

Lingenfelter had no problem doing that and more with it. Of course you could. Ling don't sell the gt7 anymore. I have used one now but not sure want to ship it cross border.

Are you running manifolds or turbo headers?

I ran my 408 at 9.5 and it was fine and now running 9.5 on my 427 and sure it will be fine too. For mostly street car 9 to 9.5 is good ratio. For track mainly where you are shooting for really high boost levels maybe 8 to 8.5 would be beter. Course if you can get e85 you can go higher and also if you run race gas at track at higher boost levels. Also if you run bit more compression you can go bit lower on timing to compensate.
I think going too low could make the car doggy around town. And I don't like
doggy cars.
