To me it means they all come out the same. Each and everyone are identical. I recently viewed a program where it was a big deal years ago to have the car parts interchange rather than be hand built for each car. They used some measuring blocks so they could manufacture things to the same dimensions. The blocks came from Sweden or near there and it was a system of things to measure. The big test was when they took 4 cars apart mixed and swapped the parts and all 4 cars ran fine. Huge accomplishment back then and started idea of mass production. Imagine if they could see CNC now.

When I was a kid all sentences started with a Capital letter but that was before CNC or is it CNN

Geneus

Or CNBC.

Ohh, so now you think you have reached "Tuner" status

For those who don't know, Chris and I are friends. so his quote above only means that he loves me. And he knows that i will still sell him G5X-3 cams. He also knows that I am much better looking

At any rate, we have two cam packages at this time. one uses stock springs, and one uses the same springs that we use in our World Challenge race car. We rev our race car to 7400rpms every shift because the rules let us, and we can't leave anything on the table.

We only use the best springs on our head packages and since we started using these springs, we have not had a single spring failure with any of our cams.

As for the idle quality, we did our first cam and picked up almost 25 hp and kept the stock idle quality, with NO tuning.

Just ask your "tuner" what he did for a living 5 years ago and you will then know if he is a shade tree opportunist and hype artist or a real Corvette guy with deep Corvette and performance knowledge.

For the East Coast Guys, I highly recommend East Coast superchargers for your cars. He even installs our LG Packages with a smile.

Thanks guys, this new Z06 is still putting a smile on my face

The new C6 Z06 looks like a power house on and off the track. Next year will be a good test to see how it holds up to a full race season.

Good luck LG...

Are those flow numbers with a radius entry on the intake port and a short pipe on the exhaust? Was 28" used for the test pressure? It is interesting to note the flow was still picking up at .650 lift. Did you guys test .700 and .750 to see where the port stalled out? This thing will make some power with a cam and exhaust mods. Be careful about the springs though as there has been several reports of broken LS-7 valve springs.

Runners should be 264cc and chambers should be 70cc.

Great info Lou! Any chance of flowing the head with the intake on to determine if the intake is causing restrictions?

Wow, those heads are flowing some air!!

For an interesting comparison, here are some actual numbers that we got from flowing a set of AFR 315's for my BBC. The heads were angle milled to 114 cc chambers (121 from AFR) flowed on a 4.25 bore at 28". No pipe on the exhaust or fixture on the intake.

LS7--------------------- AFR 315 BBC
Lift Intake Exhaust----- Lift Intake Exhaust

.300 246 cfm 174 cfm----- .300 233 cfm 185 cfm

.400 302 cfm 200 cfm----- .400 293 cfm 222 cfm

.500 343 cfm 211 cfm----- .500 340 cfm 247 cfm

.550 358 cfm 216 cfm----- .550 353 cfm 252 cfm

.600 360 cfm 220 cfm----- .600 362 cfm 255 cfm

.650 379 cfm 224 cfm----- .650 368 cfm 257 cfm


Just wow.

Im not up to par of tech specs so my question is are these stock heads better than the AFR 225 heads that were the bomb a few months back?

Rkreigh

probably. the old CNC ported LSx heads flowed in the 330+ range which is quite good 360+ of the ls7 head should indeed flow enough for 600 hp with more revs and higher lifts on the cam.

I am curious how much GM "left on the table" and with more agressive porting what might be possible. the ls7 sure looks alot like the c5r head to me which easily made 650 hp running restricted.

I would think quite a bit more potential is there. thanks LG for pushing the envelope and showing what the new LS7 is capable of!!

LG Motorsports

Thanks John,

We are not done yet. It is alot of work but we are taking the mods to this car as an R&D car step by step to document the improvements. We plan on some head work to see what is left.

Then when we get tuning, that will open the door for so much more.

Thanks

Tx Tune,

Cut this crap out - if you take the time to read Lou's previous posts it will become obvious he knows what CNC is... To call him out on the fact he refers to it as C & C is dumb... You do not know how to spell "numerically" either - so in the end who's got egg on their face? Why don't you bring more to the table than being critical of minor typos?

Lou,

I'm glad you have thick skin... This crap gets annoying fast to me. I know where my new (2007) Z06 is headed (pun intended) for some extra HP!

Lou! Geeze, that car moves, sounds great, and the brakes work really well too! Thanks for the ride; it was a blast.

Sorry Charlie ... Lou's threads are 'tuna safe'. You're in the can.

kutlow

Lou, can you answer my question as to are these heads on the new z better than the AFR 225'S that were the bomb months back?

richie427

did the read left to right.

Sorry, plain an stupid, is me well that little thing that cuts the holes, it never, leaves it's programmer hand, an never gets smaller, the cut. the test run, are always the same the program might tell a different story, might as well pick up an Ben an jerrys ice cream, with all the.
