Alright, so I need some opinions on what to do for heads/cam.

I currently have TSP LT's, ORY, and a Borla cat-back, with an SLP lid.

I am going to be installing an LS6 intake, with a ported TB soon.

Next season I want to buy a set of ported heads, and a cam to match it.

Eventually after the heads/cam I want to put a 100 shot on that, but that is not for a ways down the road, but I want to build the car now so when I do, I am not kicking myself for not doing something.

So back to the heads/cam, I was looking into going with Texas Speeds 5.3 heads, and their 233/239 cam, with 114 LSA. (114 because of the N2O).

I have heard some people have been disappointed with that setup, and have been told to look into either just getting some 243 heads, and that cam, or possibly Patriot heads.

I need opinions on what to do. Thanks.

For that relatively small a shot like that, I'd honestly pick your cam based on your NA mods and power goals, and just enjoy the extra spray power when you use it. The PRC Stage 2.5 5.3L heads are a great budget oriented cylinder head and I think you'll enjoy the gains they provide I'd consider the TorquerV3 for peak power gains similar to the 233/239, but with better street manners and power under the curve!

That combo fits great with no piston to valve clearance issues and you will not need to flycut your pistons to clear it!

Let us know if we can help or if you have any questions about the PRC/TSP line-up!

I've sat PRC's and Patriots right next to each other, and the PRC's definitely have more attractive looking port work. Patriot increases are in the 25-30rwhp range. I'm not sure on solid data for the PRC's but we'll find out soon. I'll be installing 3 sets of them on back/back cam cars within the next 3-4 weeks.

As for camshafts, it's my personal opinion that Patriot cams are garbage. Not to mention they're not cut here in the US, hence the reason they're so cheap. Go with a custom comp grind.

Josh: Are you going to have the chance to do a baseline before the heads and after without other changes by chance? Or are they all getting heads/cam at the same time with no pulls between the work?

Matt, one car will have a direct A/B comparo as it's a cam only car and we already have cam only #'s for it. The other will be a heads/cam swap. But I've got another customer wanting some PRC's as well, that already has a cam.

i would definitely go with the 233/239 cam.. i actually considered about going bigger to that cam. my buddy ran that setup with the PRC 5.3 / 233/239 and loved it.

I was just looking up the specs of both the 233/239 cam, and the torquer V3, the 233/239 cam is supposed to have a powerband from 1900-6500, aka wouldn't that be a torquier cam, with less top end?

The specs of the 233/239 cam make it bigger than the torquer cam, but the torquer is supposed to have a powerband to 6700...so I am a bit confused as to which I should go with, and why?

Sales2@Texas-speed

No, unfortunately the powerbands listed on our website are a bit skewed since they were not all rated on the same engine, same dyno, same mods, etc. The TorquerV3 will definitely peak earlier than the 233/239, have better average power and torque, and over-all better street manners too!

How does that torquer cam do with nitrous though? I have been told that you want an exhaust biased cam with N2O, and the torquer seems to be a bit more intake based?

Sales2@Texas-speed

The intake has more lift than the exhaust, which is pretty common on this platform. However the exhaust has more duration! Ask any of the nitrous guru's (a whole forum of them on here actually), and they'll agree 95% of the time when asked that for less than a 200 shot and on a street/strip combo you pick the cam to perform when NA and just enjoy the extra power when you spray it.

You're going to be happier with the TorquerV3 as compared to the 233/239 with your setup!

Like Matts saying, if your not running a big shot, there is no need for a nitrous specific grind.

Hmmm interesting cause I was thinking about going with this setup as well 233/239 with 5.3 heads.

Sales2@Texas-speed

There's nothing wrong with the 233/239...but....you can make basically the same peak power with better average with the TorquerV3! Its been proven time and time again, and makes for a better street/strip car!

Very interesting, I may end up with the torquer then. What kind of powerband do you think I will end up having?

TSP LT's, 5.3 heads, torquer, and an LS6 intake and a ported TB.

I know I am going slightly small on the intake, but I have been told it is much less of a PITA than the FAST, so I will stick with that and some power loss.

Also, on the torquer, you have the option for 111 or 112 LSA, for my setup, which do you think would perform better. Like you said, with going with a relatively small shot, and probably not spraying the car THAT often, probably lean toward a more NA based cam, so go with 111 LSA?

antonio84

Oh don't get me wrong just never seen or heard of torquer 3 with t 5.3 heads before.

I got my patriots for $600 with valve no springs so couldn't pass them up! And my buddy in a 02' z28 with full bolt ons and the 233/239 put down 400

Matt, I know this thread is slightly cluttered, but could you answer this please?
