which heads are better patriot 5.3 or patriot cnc ls6
 

i need assistance from people who actually have these heads which one makes more power ? i have a 04 ls6 cam to be installed with whatever heads i choose. also is an underdrive pulley worth the money.

With the LS6 cam I would pick the 5.3's over the LS6 styles for sure. There is a guy here locally that runs a LS6 cam and a set of patriot 5.7's and he ran a 7.6x 1/8th @ 91mph Thursday night on his first trip to the track with that setup. He goes by "ls1only" on here.

If you ever plan on going with forced induction (turbo, super-charger or nitrous), you would want 5.7 or LS6 heads. The reason being is that the 5.3 heads increases your compression from 10.2 to 10.8.

However, if you never plan on forced induction you could gain a little hp from the extra compression.

Good Luck,

Al

You can run high compression with Nitrous. Just need to pay attention to the tune on the gas.

As Gomer stated the 5.3's will wotk great with a smaller cam. If you are going to run a big cam like a g5x3 or a tsp231/237 the LS6's will work great. You can get the LS6's from patriot with a smaller combustion chamber to bump the compression up as well.

Hey Brad you've got the same setup as me... :usa: BTW what the hell is up with that weblink in your sig???? Who did your tuning? Do you have access to HPtuners or Edit? I'm having a few "bucking" while cruising at 0 % TPS issues. I would really like to take a look at your tune if it is available.

Matt I tried to send you a PM but your box is full. Clean it out Bro!

ok after reading a lot of posts on here i am going to sell the ls6 cam and since i am running a 125 shot of nos i wont get the 5.3 heads i am for sure going to get absolute speed stage 2 heads with the 2.02 valves now my question is what cam do i need to make say 400 horse at the wheels but keep in mind it has to be streetable i have a 94 z that i put the lt4 hot cam in and to me its just a little too much. also does anyone have any idea how much i could get for my ls6 cam its brand new in the box thanks.

by the way this site is awsume it really kicks a#@ :hail: so thanks for all your experience and info


stage 2 ls1 heads from absolute speed

Try a MTI SII cam , I just dynoed 390 rwhp through cats with stock heads . I think you'll hit 410 easy. On a 75 shot dry it did 472 RWHP . :judge:

With a new fuel pump Im going to kick the shit outa 550 rwhp :devil:

Its a 240 220 581 581 116 LSA

does it have any idle issues or is it quite streetable. thats some awsume numbers do you have the part # for the cam

cleaning now give meabout 5 mins.

The stealth II cam is great. You can't even tell it's in there until you get into the throttle...Sounds stock too. :pimp:

sounds like my cam but i went to lg motorsports and couldnt find it is there a different name for it or do u know the part#
ok i found the cam on mti site 399.00 what valve springs did u go with for this cam

It is from MTI...I'm not too sure if it's on their site. I'll check it out for you.

I beleive you will be fine with the LS6 springs...I would call David tomorrow at MTI and he will get you set up. Like I said I beleive you will be OK with the LS6 springs, or you can opt to go with the comp 918's. Enjoy the cam!

Matt

I would upgrade the springs to 918's or similar :cheers:

Well, did you give them a call????

no, but i checked out the web site and im gettin the stealth 2 might even get theyre new g1 and theyre stage 2 ls1 heads. theyre hand porting looks like the best iv'e ever seen, and every one here seems to say only good things about mti thanks for the info :hail:

does anyone know what brand of stall to use with the mti setup and what stall speed also does a stall drive the same as stock at highway speeds thanks one more thing anyone with 3:73s what are your rpms at 60 and 70 does it take away any of your top speed my 3:23 will get me to 150 quite easily

What are you main uses for the car...for instance do you just drive it on the weekends with occasional trips to the track or is an everyday driver...what kind of times do you want to be able to run...what kind of tires are you running??? answer these and we can give you a better recomendation on the stall...be as specific as possible on the car and it's uses, and your expectations.
