if u get rid of the 224/224 i may b interested lol
Other than that... you might want to look in to a cam with a longer duration on the exhast side as well.
I had a GT70 STS on my 98 formula with 12psi pushing 605rwhp to the rear. Thing is I had a hard time getting it to spool fast. I would be full boost at about 4.7-5.3k rpm. I am SURE i could of spooled faster with a better cam. Dont pick a cam cause someone says it gives you better hp... Get a cam that will help you spool faster. I think 14.7psi is the # that doubles your hp. If you pick the cam with the faster spooling I am sure the other might have 20rwhp or so more but your under the curve hp will rape them.
As of now, go with what you know and that's the ls6 cam works. Talk to some dealer of STS and see what they say.
I have no dyno numbers yet.
My cam is near identical to z06 cam . Might have different ramp rates or lobes or something.It is compatible with 1.8 rockers so went with some to give me more lift. Running 8019 valve springs good for 650 lift just to be safe.
01 ZO6 cam: 204/211 .525/.525 -116 LSA
Lingenfelter GT2 205/212 .540/.540 –116.5CL
02-03 ZO6 cam: 204/218 .551/.547 -117.5 LSA
Lingenfelter GT2-3 207/220 .571/.578 –118.5CL
05-07 ZO6 cam 210/230 .561/.557 –120.5 LSA
Lingenfelter GT7 208/230 .554/.546 –121CL
Mostly they use the gt7 these days.The gt2-3 was their choice previously for super or turbo.
I got my gt7 for really cheap used so no complaints.Otherwise likely would have bought the gm cam as they are cheap.
"My car was a handful when it made 680rwhp (9.4@143) so I have yet to see what it will be like with 867rwhp.
The beauty about turbos is that you can adjust the Hp with a touch of a button on the eboost2 controller.
I have the car tuned by one of the best tuners in the country.
here are the Hp setting:
1.606rwhp -640trq - 7.6 psi. 91 pump gas ( my wife drives the car with no problems
2.656rwhp -670trq 9.0 psi
3.707rwhp -773trq 11.6psi
4.736rwhp -812trq 13. psi
car makes 735rwhp(over 840 HP at the crank) on 13psi 812rwtrq(over 900 TRQ at the crank) ..car is a beast. will do the 1/4 LOW 10'S AND over 138+ mph.
condition is 8.5 /10 (its an 2002)
Here is the list of mods:
I just had a wideband installed- 250.00 plus install
( so the picture with the gauges has a wideband instead of the second boost gauge.)
Everything is done RIGHT - no corners cut!!
L.A.P.D did the install and they have done over 50 APS cars.

Cam is not really going to add much power.Turbos will reach their max power and thats that. But you will be playing with lope, idle, tuning ease,cam surge, and area under the curve and moving powerband around a bit with various cams.
A real crappy cam choice could bleed off boost maybe and stop you from reaching full power potential of the turbos.
