haha, awesome video..

I got a new best with my LS6 cam at almost 5400 ft DA the other night.. for those curious thats about a 11.6x @ 117+ at sea level.. on DR's

My car runs on avg. 7 tenths quicker and 3 mph better with the cam and gear change (3.73 to 4.10) than last year in the summer.

The LS6 cam is well worth the money IF you get one cheap, and install it yourself.

 

No offense, but an 11.88 with heads and cam isn't wholly impressive. You would surely go quicker/faster with a more aggressive aftermarket cam.

 

I talked with my cousin who works for Wheel to Wheel. I asked him about the 02 zo6 cam and he told me that most of the LS1's they build for people have cnc z06 heads and cam. I guess they are getting 500 plus out of the set up. With a pretty much stock bottom end. So thats the cam I going with. Anybody got a good 02-04 zo6 cam they want to get rid of? Pm me and let me know. Thanks

 

I happen to know Z28SSMAN and this is the argument I've heard over and over...

What people forget is that the LS6 heads and cam are off the shelf GM parts and the car idles like a bone stock LS1. I think 11.88 isnt too shabby and if you seen his car, you would probably suspect low 13s, maybe high 12s. I think he may have already gone faster since then...but I cant say for sure.

There are plenty of cam only cars around here that should be in the 11s easy, but arent....and they have the biggest lumpiest cam you can get. If both cars ran high 11s, I would choose stock idle over a lumpy idle anyday.

My $.02.

 

I would choose lumpy idle, as would many others. But that is just personal preference.

There are TONS of aftermarket cams that don't lope hard but make much better power than the LS6 cam. You can even make more power from a different cam and still pass emissions in california.

11.88 is never shabby for a NA 346, but a cam swap could definately improve upon that, without ruining the stock idle.

That is my main point.

 

Z28SSMAN--what mods do you have in your car?

 

His public profile reads:

 

You sound like quite a few locals who "aren't impressed" with my car. The funny thing though is they are considerably SLOWER. I guess their "more agressive cams" haven't helped them. lol

I'd agree with you if it were a true "heads and cam car". The heads & cam are factory GM off the shelf parts. Basically a Z06 engine.

Not to pat myself on the back, but how many cars with a raceweight of 3740 with 363 at the wheels go 11.80's with an M6? This is with 17" wheels and DR's & deCarbon shox.

I see you're in the "11 sec club". How far into the 11's is your car? What did it take in comparison to my set up to run your ET's?

 

I've run a best of 11.92. (in June, hoping better in fall)

Cam only. (untouched stock heads) Large cam, but that's the way I like it. It's an automatic with a biggish converter, 60' is almost identical to yours. The 12 bolt and hard launch really helps the M6's catch back up to the stalled autos at the track. You can read everything in my sig and the link in my sig.

 

Not to get into a pissing contest blkz28spt, but now that I look at your profile, I'd match my package against yours anytime you want.

I Will agree with you that most likely, a better cam would make my car quicker. I guess I didn't like your "tone" when you say my "heads and cam" car isn't impressive.

I have done the drag racing thing for years and I KNOW what is impressive and what is NOT.

Thanks for your comments 99sleeper.

 

In what terms would you match packages? We are running nearly identical times at the track, but my heads are stock (and rear end). And I love driving my car around on the streets. The cam/stall combo is 100% streetable and behaves very well.

 

There is no disputing that automatics with converter are generally quicker than the M6. As far as the "hard launch" comment...my launch was only at 4500...not 6k. The track was not going to allow me to launch any harder than that without blowing the tires off. With slicks and a 5500 launch, the ET would no doubt be better.

Keep in mind...I have 363 rwhp, you have 385. Although automatics typically trap lower than M6, I wanted more than a 112 trap speed. Thats why I went with the 117.5 LSA for the top end pull, I love to pull up beside "big cam" autos like yours from a 60 roll.

I see alot of racers run a quick ET ONCE and then imply that their car is going to run that consistently. I ran 11.80's three times on the same day. It may be somewhat easy to do with an automatic, but is extremely difficult to do with an M6.

Wider LSA or not, big cams will make more top end power than an LS6 sized cam.

My last four consecutive runs were <11.9's, spanning two different days. Consistency is more difficult with an M6 for sure, but a strong clutch/rear, sticky tires and PRACTICE make it possible. I'm sure you are aware of that practice part.

Let me hit better weather and add some heads and I'll take you from that 60 roll. Besides, the real races are from a dig.

 

I just looked at your cam specs. You're running a 237/242 with a .603/.609 lift cam and you're trapping 112? Mine is 204/218 with .551/547 and I've trapped as high as 118 more than once. (I found out why mine was only trapping 114-115.90 on the videos and have corrected the problem). By the way, I have stock tb and maf and stock pulleys. I guess the GM engineers know alot more than people give them credit for.

Well, I like my chances with my M6 against yours even with heads from a 60 roll.

By the way, nice car ya got there

 

112.8, in June weather.

A4 vs M6

Stock heads vs LS6 heads.

Also keep in mine is a 98. Most stock A4 98's run 13.5-13.9 bone stock. I only ran 12.6 @ 106.5with full exhaust, lid, CAI, ET streets, !FSB, 3500 stall converter, etc.

The cam, LS6 intake and ASP underdrive pulley with dyno tune dropped 0.7 from my ET, and added 6.5 mph.


Edit: You know, I could say "you have LS6 heads and my ET is nearly identical to yours, but my heads are stock."

 

Hey if you're happy with 112 trap with that big assed cam, then that's all that should matter, right?

How much power do you think the LS6 heads are worth? You make it sound like they are ported Stage 2 or AFR or whatever. If you do research, in stock form they MAY be worth a whopping 15 over the LS1. Your ported TB and pulleys are prolly giving you more than what my stock LS6 heads are giving me.


And.... I ran 12.36 @114.36 without headers, with full exhaust with the inferior LS6 cam, stock LS1 heads.

 

Again, 112.8 in a stalled A4 in June. Or maybe you are right and my car has a mph and my cam is a poor choice. After all it only added 4.5 mph.

I think LS6 heads are worth more than 15 hp over stock (98) LS1 heads. Pulley gives up to 10 hp and ported TB, well, 5-8 maybe?



Full exhaust includes headers.


You are missing the point. If you went with an aftermarket cam you could make more power, ET lower, MPH higher and retain your stock drivability.

Let's put it this way. Do you think I could swap my MS3 for an LS6 cam and not lose performance? HELL NO!
Could you switch to a 224 and gain performance? Hell yes!

This whole argument is stupid. Do you know how many stock internal guys could beat us? You can't just look at it the size of the cam, see a smaller cam running equal or better and start bagging on everyone with the larger and not better performing cams. There is SO MUCH MORE to how a car runs than the cam.

 

I never said your car is a turd or your cam is a poor choice. I have made my statements not with bench racing, but facts.

All the engine builders and data that I've done research on indicates that the LS6 heads in stock form are good for about 15 hp (not rwhp) over the LS1 and it has been recommended that the best bang for the buck is to go with a worked-over set of LS1 heads rather than the cost of buying a set of LS6 heads.


I don't know what your point is, but my car ran the 12.36 with stock manifolds, cats and y-pipe through the factory SLP Dual-Dual. It currently has Kooks and catted y-pipe with the same SLP factory exhaust.

Well, that's your opinion. There are many guys in this area running the 224 cam and are running SLOWER than my car. In fact, I don't know of a single car with the 224 cam in this area with comparable or higher power running quicker. So why the hell should I switch to a 224 cam? I'm not going to do it because it's the "popular cam". That would be just plain silly. Based on what I've seen in real life, if I did decide to change to a different cam, it sure in the hell wouldn't be a 224.

There's no doubt that there are "stock internal guys with quicker ET's. I don't know how many are running the M6 with 3740 raceweight, stock suspension & 363 rwhp though. If you know of any, let me know.

I didn't start this YOU did. YOU are the one that said my car isn't impressive for a heads and cam car. I only reminded you (along with others) that my car isn't what you would refer to as a typical "heads & cam car". Although you are entitled to your opinion, I am certainly entitled to mine.

Are we done now? Or do you want the last word?

 

No other car running as quick or quicker than you, using a 224, in your area doesn't really mean anything.

Do you honestly believe the LS6 is a better performance cam than a 224?

 

how does it not mean anything?! blkZ28spt....this is getting old. the points you are trying to make are stupid. if you like a big cam sound with so-so timeslips, that's your choice.

a good setup is a good setup and last time i checked, the facts are the facts...

:yawn:
