Just like the title says I am trying to find the best Patriot Head to mate to a G5X2 cam. Obviously I am assumnig their LS6 head but what chamber size etc. This is going on a 2001 LS1 motor that is going to be sprayed the forged and possible stroked this winter so I want a head that may cost me a little now but will pay off the most next spring.

Help guys I am very excited about Patriots new LS6 heads and want to take advantage of their GREAT prices.

Thanks
Mike

I got the 59cc stage 3 LS-6's. It gives the highest compression without milling, the biggest valves offered by patriot, and 315+ cfm should adapt to a stroker very well. Should make excelent power on the stock bottom end also. I plan on running the G5X-2 myself if the X-3 isn't out soon. Check back in around Oct. 4th. A guy on here will be dynoing his patriot LS-6's and the TSP 231/237. You can use that as a template.

Keep in mind that 315 CFM is already measured on a stroker It would be interesting to see what the flow numbers are on a 3.905 bore.

Give Absolute Speed a call, they have several 440-460+ rwhp cars with the G5X2 cam, a proven combo. I suspect dyno numbers with a G5X3 and AS heads will be coming soon.....

Not flaming, just don't think that a standardized CNC program can fit all cam profiles, that there is something to be said for porting the heads to match the cam. A 230/224 cam should have different head flow requirements than a 232/240, IMO. You rarely see any exceptionally high HP numbers or low ETs out of a CNC head (TEA, CNC, Patriot), most high numbers and low track times are from hand ported heads (MTI, AS, GTP, etc).

This is just my .02, no flames, just my opinion, and you know what they say about opinions

Flow diffrences will be minimal if any. I've been through this with others before and this was the final outcome.

This is why many would get a cam mathched to the heads. The cam should alway be the last item picked in a combination. Personally I could care less about paying for a name, a cam desighned for a given set-up will always out perform set-ups in the same size division, as long as the person designing it is good at what he is doing. I'd rather pay $2 g's and have a cam ground custom to my head measurments then spend $3,200+ and have a cam ground to them. Performance diffrences will be very minimal to none if the right person is doing the custimazation.

Understood, and don't take my opinions as a flame. My real opinion is that CNC in Fl. should not be put in the same catagory as TEA and PP. These 2 put actual R&D in there products. I can't say the same for CNC in Fl.

Any other suggestions??

The G5X2 cam will like the compession of the small chamber.A 59 cc chamber will give you around 11.2 comp.

beast96z, you say you should match the cam to the heads. well alot of brand X heads dont work with the bigger cams like the g5x2. if you do a search there were a couple of heads one being a cnc head that made almost 40 hp lower then a head ported for the g5x2 cam.

TVWilkes

Our heads have worked well with larger cams.In the coming weeks there will be a few cars running big cams.

I guess I'm confused at what your saying and I guess you didn't understand what I said. If your brand X head would have gone to a compitent cam grinder, then I'm sure they could have gotten more power simply because the cam chossen wasn't efficent in the set-up. My point was, if you or your head porter knows all the charecteristics of your heads, a custom ground cam will be more efficent in the set-up than an off the shelf cam. Why spend $3200 on heads and $400 on a off the shelf cam when you could spend $2,000 and get a custom ground cam matched to the heads and make better, more efficent power through out the curve?

Thanks Terry that was what I was looking for.

hey beast let us know what your compitant cam grinder picks for yah. im real curious to see what spec cam he will choice for your heads. are you giving him your heads to flow test them?

If I pay $500 plus for a cam + someones knowledge, I believe I'll keep the numbers for myself. I'll show you my dyno sheets and time slips though. I feel that Terry's superflow 1020 will be pretty accurate. I can have them tested here in town for comparison though. It will be a large cam designed for best "under the curve" power, not just peak.I'm not trying to say anything bad about the X-2. I think it is a great cam, espeacially when paired with absolutes heads cause Jay an Lou have worked together to put together a great package. Although I feel that my Patriot heads will make the same power for less money with my cam choice.

The ls6 style head will perform with larger cams.I can't wait for the Thunder shoot out.It should be a good event.
