ok just doing this for fun i have a 01z28 with a motor out of a 04gto stock bottom end 40k miles currently has lpe heads cam setup heads are cnc ported 243s with 2.02 1.57 stainless valves
comp dual springs titanium retainers
1.7 roller rockers...
cam is a lpe gt11 215/231 .631/.644 118.0cl
comp cams adj timing set
ported ls6 intake
85mm bbk tb
fast fuel rails car has full bolt ons
pacesetter 1 3/4 long tubes w y pipe
magnaflow catback
car is a 6 speed
4.11 gears
racetronix 255 in tank and hotwire kit
car made 434 running out of fuel on the top end before the fuel pump and hotwire kit im looking into putting in an ms4 or possibly going custom grind from patg wondering what you guys think i will gain form the cam swap?

 

well those are good numbers and that cam looks faily aggressive to me as far as lift

how much are you hoping to gain? my first impression makes me think you are going to be disappointed after the cost/work of the swap and potential of losing under the curve power but I'm no expert by any means

 

forgot to mention that those numbers were through the rossler 4l60 with a yank ss3600 i recently did the swap to a 6 speed

 

I have a G8 Automatic gear 4 speeds to handle over 600 RWHP
Aluminum Engine ls2 engine
Full length Header and Exhaust system from Xforce performance.
OTR air intake system from JHP performance.
Cam Gt11 from Lingenfelter Performance.
AFR heads 225 62cc with a 92 FAST
SLP under pully
Lower Kit form JHP performance
My car made 465 Rwhp

You made nice numbers for a 4.10 you should go with a GT1-1 i see you making 7+ more rwhp

 

+1 You would probably gain by adding a fast intake and you wont have to worry about losing power under the curve or PTV issues as a result of running a Ms4. If your dead set on a new cam I would go patg or Geoff at EPS they can hook you up.
