would this intake and these heads work?

engine is stock right now; would an ls6 intake work well with patriot stage II ls6 heads on my ls1? would a 22X/22X cam be good with that or something bigger/smaller...can that get the car to 350 rwhp or more? thanksss

Honestly, the car will make well over 400rwhp with that setup no problem...more like 440-450 with a good cam. I'd use a low 23x/23x cam with .600-.610 lift for something very streetable....look into the Futral F-13 or F-14.

PP doesn't really go by stages anymore... have you checked their website lately? These look the most promising: https://www.patriot-performance.com/...&cat=37&page=1

The 2.055" valves are nice and the 59cc combustion chambers will put you around 11.3:1, which will be great for a 93 octane tune.

If the car is stock, your first mods should obviously be a full exhaust setup including LT headers and catback (Pacesetters are $399 and nice), a LID/CAI, and lastly a dyno tune when you get it all together.

wow. alrighty thanks. i mentioned the 'patriot stage II ls6 heads' because someone is selling them locally. i know little about heads, but are the ones you have posted there completely assembled or would i need to get other parts to go along with the engine too if i went with that cam you mentioned? would you recommend getting a better clutch with that much power over the stock one?

EDIT: the heads are being sold locally; asking $900...I'd like to save the money if they look good; I haven't heard back from the guy yet

stock clutch won't hold that much power for long.


something else to consider is that intake runner size on those heads...they say 227cc. which is decent size. you'll have sluggish low end, compared to other heads.

will make a nice dyno queen, but may not be ideal for street use.

lots to consider when talking heads

what about the ones i mentioned that are listed locally? would you recommend something else for similar power with street use? or would street use sacrifice a good chunk of the power?

Patriot heads are junk. I don't care what others around here recommend, they are crap. From hundreds of dropped valves to valve guides that have been glued in and reamed to fit - they have a horrible rep for quality. If you want an inexpensive ported stock head look at Texas Speed or Livernois.

jmmullin - Talk to Jason C. in your service department (recent transfer from my store, looks like Woody from Toy Story) about his Firehawk, and ask him about my car

Finally - $900 is a bit steep for those heads, 243s or not. I just sold a set of ported stock casting GTPs for $850 shipped that blow the Patriot heads away in port flow and velocity.

ouch. trash on the patriots. good thing that guy hasn't gotten back to me yet i guess...

marc -- is jason a tech or a service consultant; if its the service consultant guy i've talked to him a couple times and he's pretty cool...does kind of look like woody. maybe i'll just walk in and yell WOODY and see if he turns around.

then again that would be awkward if nobody turned around...

do you have any particular H/C combo that you believe works the best for a car that I usually just drive once or twice a week on the public roads?

and finally did you get your transfer info taken care of or are you not coming to raleigh anymore?

Jason is one of the recent technician transfers (there's been about 4 recent ones). As far my transfer goes, I want to talk to Cormack first, and possibly stop by one weekend to check both the shop and a few houses out first. Hopefully they will convert the shop to a brand specialist type deal so that I can keep all my gravy Ford work. Maybe I'll bring my TA down, but it drives VERY different from a manual trans car

About recommending a combo, I don't know what you're looking for or how much you can tolerate. Jason will surely let you ride in his (if he brought it yet), and you can make a call then if you want something a little less aggressive.

The ones I have posted are assembled.

Honestly, if you don't even know that you need an aftermarket clutch to hold that kind of power, buy some bolt-ons first and come back to talk about internal modding in a few months

I seem to remember PRC having the same valve issues that Patriot did. As in both cases, it was a component issue and nothing Patriot or PRC actually did.

The PP valve guide problems I heard about were pre-Gunther.

The guide issue I referred to recently surfaced with someone local. Heads less than 1 year old. The valve problems were a couple years back, but they were putting in generic Chinese valves and selling them as Manley.

The day someone can show me a 10 second NA 346 with Patriot heads I'll eat my words. There are literally dozens of PRC headed 346 cars around here in the 10s, naturally aspirated at or near full weight.

I actually mentioned the clutch thing knowing that I would need a better one, but mainly to avoid the inevitable jack*** poster that has to throw his .02 in by saying something smart like..."do you expect this to hold on your stock clutch that could have 85k miles on it????" but i guess you just covered that anyway. haha j/k... everyone has been very helpful around here, contrary to other forums i have been a part of. i definitely appreciate the comments like "XXXX brand is crap. and so is this" I guess i will eventually end up going with a brand you all haven't mentioned at all, and then let you know by my own experience that they too, are crap.

but while i'm on the subject of 85k miles, is it cool to just introduce something like a new set of heads and a cam to something that broken in?

marc- i asked the service consultants if they knew jason today, but nobody did; i will probably check with either cormack or one of the tech managers tomorrow if i go in, or thursday when i go in. what year is his firehawk? I saw a green '95 come in last weekend i worked and it had 25000 miles on it; they guy didn't want to sell it but i talked to the sales guy that was his consultant and he said the dude would let me have it for 12grand. I later did some research on the non-official wikipedia and there was only one green one made that year, or maybe it was a year close to it idr exactly...but it was a hawk so it must have been rare i suppose...don't know much about them. This one was sweet though...did they have the lt4 or 1? or somthing different?

as for what i'm looking for particularly: my brother has a 99 mustang that he swapped a gt v8 into and runs either a 75 or 100 shot in; i'd guess total output to be around 350 rwhp ish. i want something like that, on motor only. i have a suzuki sv650 which is my daily driver, so i only plan on driving my car when it rains so i dont get wet on my bike. therefore drive-ability is an issue, although not a HUGE one. thanks for the help everyone

2001 Firehawk. It's black with the Firehawk package accents in gold. He's pretty quiet, so some people may not know him yet.

bolt ons
ported 5.3 heads
228r cam

great street manners and should make 430rwhp

more aggressive on a big budget....try cam only.

something like the tsp Torquer 2 or the Futral F14...or maybe the high lift F14 that kraest now has...seems to put good numbers down (no surprise).
