Ls1 5.7 cam & turbo setup
Am about to upgrade my ls1 with good cam, i have found this on ebay by howards cams which is coming on 274/280. 224/220
Valve lift 609/604 and also they offer 612/604 ?
Next with the turbo setup , i have selected s400-72 /1.10 a/r 83 turbine wheel any recommendation ? How it will work with 317 heads and stock bottom ?
My goal to hit 500 to 600 rwhp
It is a weekend car street car
Any recommendation on which gasket to use ?
Any thing i can added to the bottom to keep it safe in a budget ?
Max boost will go 10 to 12 psi

i did exactly what u are trying to do but i took a slightly different approach to reach my hp goals which i was able to do i make 610 on exactly 10psi. i used an iron 5.3 bored to ls1 bore size but i did not use 317 heads inused 853 heads with -3cc pistons which is pretty much flat top pistons. my truck doesnt feel gutless out of boost because the compression ratio stayed the same. i used an on3 88mm which is a small turbo not a real 88mm at all. with 3.27 gears and 10lbs i am at 600 to the wheels l use a 230/230 615 on a 115 works good 80lb injectors stealth aeromotive fuel pump all.in all simple set up drives well in the street spools up fast th400 3800 stall nothing real expensive mostly second hand parts
And I believe 1.10 A/R is a bit on the big/laggy side for an LS1.. around 0.8 A/R max. would be better.

LEAVE THE STANDARD ONE IN THERE.
You don't need some fully sick hectic cam on a turbo motor. People with LS1 turbos make a crap load of power with STOCK CAMSHAFTS.
Forget what your friends are telling you. You'll just be throwing your money away on an aftermarket cam + stressing out more for nothing.
Concentrate on your turbo setup, make sure you get the right sized turbo, wastegate, bof, exhaust, injectors... and the "insurance/strength" side of things like valve springs...
FORGET THE CAM! End of story.

Stock cam, stock heads, stock valvesprings.
Don't touch the long block. Don't complicate things.
The Borg S472 will get you there just fine.
Stock cam, stock heads, stock intake, stock short block etc. All just fine for 500-600rwhp with the turbo you've chosen.
I would take the stock springs out and go with a PAC 1218 spring kit which utilizes the OEM retainers and OEM one piece locator/valve stem seal.
I sell the PAC 1218's for 175 shipped if you are interested. I'd also go with an aftermarket 7.400" push rod as well. I sell the push rods for 95 bucks shipped again if you're interested.
