Ls1 5.7 cam & turbo setup Hey guys
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

Umm.. I thought aftermarket / more aggressive cams was a no go with turbos.. better to keep it stock or very similar to stock.
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.

You can get turbo aftermarket cams made specifically for turbocharged vehicles from BTR liljon ect and they are better for turbocharged cars than a normal cam, now a NA aftermarket cam would be bad for a Turbo car yes. Like my aftermarket NA cam would be horrible for my turbo build right now.

WHY are you so OBSESSED with getting a damn cam????????????
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.

Id buy the valve train components before i buy the actual cam, like springs, lifters, seats, trunion upgrade...ect...

Don't touch the long block. Don't complicate things.
The Borg S472 will get you there just fine.

I personally wouldnt trust the stock springs to keep the valves closed under boost but thats just me, always over engineer your build so it doesnt break under load. You want a 600whp car? make it withstand 800+ so it will never break. Thats just my two cents. If you are on that tight of a budget dont build it till you can because you will just be fixing **** later anyways when it breaks, build it once, build it right. Id go BTR .600 springs? think thats what i have...also 1 piece pushrods from BTR or whoever you want does not much matter. Might be .660 springs..i can take a picture later and post it.

you can get 500whp without boost, why bother with it if your goal is so low? Do nitrous at that point, cheaper, less work, and far less of a hassle tbh...at that point you just let the car do the tuning for you once you get the spark plugs worked out. Hell im at 435ish whp with just a cam, exhaust, headers, SLP lid, SLP CAI, if i threw a 100 shot at it id be close to 550whp.

For your power goals an aftermarket camshaft is not needed in any way. Now, if you wanted to have some sound to go along with the build and turn some heads at stop lights then yes a camshaft would be necessary.
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.
