I plan to get a head and cam package from TSP. The 90/90 setup is quite expensive, although I plan to do it someday. I will plan to get a vararam, LG longtubes, and clutch to go along with this package.
I understand I'll be losing some power and breathing without going 90/90. Can anyone tell me the difference as well between the:

stage 1 ls6 heads cam package,
stage 1.5 5.3L heads and cam package,
and
stage 2.5 5.3L heads and cam package?

I'm still a newb. I want about 445whp without nitrous. But I plan to keep my ls1 shortblock in stock form...
What package should I go with? And what cam without having to aid piston work?

yes you can

You can probably make 450rwhp without the 90/90.

You should start with LT headers, CAI and a good tune...

Then get a heads/cam combo that optimizes your DCR. most go with the AFR 205's.

Do a search for a thread by PatrickG regarding a 500 rwhp Recipe. Very informative!


All it takes is money, money , money.

GEOFRC

This is good to know.

My main concern is keeping the shortblock in completely stock form. I don't want a cam that I have to modify the pistons in any way, shape, or form.

I'll search all threads made by patrick g and will read as many as I can for now.
What is DCR?

you could save some money and get the new weiand intake coming out. It was at SEMA and looked great, oh and the best part is that it is going to be around 600.

You could get a 22X/23x cam, some 205 heads a new intake and TB. You should be very close to your goals. Remember you can make killer power w/o a huge cam, and it will be more streetable.

You dont have to get the fast 90/90 setup to make good power. Its just when you change your heads and cam the fast setup is going to produce a little more power for you all the way through the rpm range. I put down some good numbers through an unported fast but, you already knew that.

GEOFRC

Yes^

Thanks to all those that posted. I'm again, sorry for such a newb thread.

Why does TSP not post the cc's for their head and cam packages? I'd like 205cc heads but don't wish to spend over $2k on just the heads. If one of the three packages TSP offers is 205cc then what cam should I select so that I wouldn't have to modify the pistons, yet still achieve over 440whp without the Fast 90/90?



P.S. I don't know what cam to use if I plan to eventually run a 150shot...

The Stg 2.5 5.3 heads and the MS3 is a proven combo that makes over 450 RWHP. It also doesn't require flycutting the pistons

GEOFRC

Oh well that's nice.

I thought anything above 600 lift requires flycutting the pistons???

i was looking at those same kits also and was wondering if anyone is using one of these kits and what kind of power they make also. I am shooting for the same goal around 435-450 rwhp with still being street friendly. Would run ls6 intake, pacesetters, and tsp ory also.

GEOFRC

Once again,

I thought a Magic Stick 3 cam required flycutting the pistons?

I actually LOVE the sound of the MTI X1 and R1 cams
Here are the specs for the two:
X1 230 227 .591 .571 112
R1 232 236 .575 .578 114

Could I use these cams with PRC 220cc 5.3L Stage 2.5 CNC Ported Heads safely and effectively? I want as much top end performance as possible. With lots of midrange.

Thanks so much LS1tech!

I was told by tsp that if you run bigger valves in the head you will have to flycut the pistons. If you run stock size valves you will be fine. I originally bought the ms3 but, when I found out I was going to have to flycut I decided to find another cam.

GEOFRC

Exactly.

Now I don't know what you all think, but I found this video of a local here in Houston from MTI and if you watch the video it names his mods and his numbers.

He put down some good numbers on his stock Z06 heads with just an MTI cam and bolt ons.

I'm going to talk to MTI and some technicians and see if I could perhaps just use the LS6 intake manifold, a vararam, full exhaust, the LS6 heads upgrade, and the MTI cam upgrade to see what I can do and what I can't do...

I'll let you all know as soon as I find out.

GEOFRC

I just called them.

The LS6 intake manifold, LS6 heads, and MTI cam will work fine without having to flycut the pistons.

with the tsp 2.5 heads and a cam like the t2 which is i think232/ 234 on comp xer lobes you should be 430+ with the right scr/dcr and still not have to spin your motor past 6500 to get peak results. get the heads with 60-62 cc chambers(or what cc you need to get your dcr up to 8.6-8.8) with a set of .040 cometics and you should be in great shape .is 93 octane available in your neck of the woods ?

GEOFRC

Most definitely. I live in Houston, 93 octane is at every pump station at every corner of the freeways.

Thanks for the info.

this will get you closest to your goal without the fast 90/90

GEOFRC

Thank you. What cam would be best without flycutting the pistons? Out of the cams they offer...

i have the torquer 3 and no PTV issues so far with the 2.5 5.3l heads

90/90s are stupid

your LS6 intake is fine or you need to go to a single plane carb intake.
