228r cam 5.3 stage 2.5 heads

[stanksGTO]

Im looking to getting a head and cam package from texas speed and right now im looking at getting a 228r cam 114LSA with the PRC 5.3 stage 2.5 heads. what kind of power gains am i looking at? Also what would be the difference with going with the ls6 heads and maybe a 112 LSA instead.

Right now all i have on the 2004 Goat is:
JBA shorty headers
JBA high flow catted mid-pipes
flowmaster cat-back
K&N cia

I also plan on getting the ls6 intake manifold and ls2 tb

Hey i dont have a goat, but i ordered the 5.3 heads from them, simply due to the flow numbers. I also got the MS3 cam 237/242 /.603/.609 on a 112. Its nasty.. I also looked at the LS6 heads, but for the price and flow numbers, i went with 5.3.. Call Jon and talk to him.. they have great customer service, and very knowledgeable.I also had them mail order tune my CPU till i could get to the dyno.

Sorry mine were also the 5.3 2.5 upgrade springs and also rods..

Let me know how that turns out ... sounds fun i still got like 6 months on my secound iraq tour so i wont be able to put my heads and cam on anytime soon.

Hey man,, Not to sound gay but thanks for your service..

Anyway,, here is a vid of it.. My wonderful brothers excellent video talents.. HA..

In short, you are going to see a substantial power gain from that combo. Check with TSP on the PTV clearance with that cam and perhaps you can mill the heads a bit.

I recently installed the Stage 2.5 5.3L heads (milled to 60cc) along with a ported FAST 92 intake and netted +45 rwhp and +20 rwtq. Unfortunately, since both were installed at the same time, it's tough to say exactly where the gains came from, however given that my setup is geared for power down low (rather than at 6,500 rpm), I imagine the bulk of the gains came from the heads. The torque curve is absolutely sick.....at 2,700 rpm I'm already over 350 tq and then it climbs gently over 400.

I would say prob.. from the heads. I hear that the FAST flows alot of air, but not much more than the LS6 which all of the 02's had anyway.. Did you do your CAM as well or just the heads...KD

incorrect info from whoever told you that...

it flows substainally more air than the Ls6 intake. when i swapped from my Ls6 intake and stock TB, to a FAST 90/90 i gained 35rwhp/16rwtq (old #'s were 409/386)...

im running ls6 stage II heads and a little 224 cam, and it made that much of a difference...

i enjoy laying down more power than people running larger cams and 5.3 heads...

I'd ditch the shorties and get some longtunes.

[stanksGTO]

yeah got the shorties not to long ago ..... already regretting it but i think they will be enough for what i want.

man you guys got me drooling over here.... I can't wait till I have the funds to open my motor up and swap cam, heads and intake. hey thank you for your service over in the sand box man, keep your head down, gun clean and come home safe!

saw the vid and your car sounds sick.

How much are you at with the stage two heads and who did you order them from...

Patriot Stage II Ls6 "stlye" heads (59cc), bought them new off a member of this site back in Jan 2007 for $900 and installed them mid Jan '07...

here is a video of my dyno run after the FAST 90/90 was installed last August:

go with ls6 heads and a nice cam... my friend made i think 20 hp and 10 torq with ls6 stage 2.5 than 5.3

[2002chevycamaroz28]

what if i got the stage three ls6 heads (see i was looking at these heads from slp and afr they teamed up and made them it was a head and cam package but i called to get them the other day and they had discontinued them i wont the best bang for my buck ill pay 3000 for a set of heads that will give me a hundred horse power)

[OnEbAdReDSS]

Stage 3 are pretty radical they have huge valves and big ports... you can run them but if i am not mistaken aren't they really made for a stroker kits?

[OnEbAdReDSS]

they highest i think you should go with a stage is 2 to a 2.5.. 3 is kinda overkill

[2002chevycamaroz28]

but see i wanna go wit a supercharger it, Bassicaly i wanna get between five and six hundred rwhp but i want it to be a everday driver too what do you kno about the L92 heads
