My car 02 Formula
best et as of May 18, 07 weeks ago 11.41, 1.6- 60'
Tr 224-224-114, Harland sharp rollers, stock bottom LS1 and stock heads,Vig 3200, et streets ( I need to lower pressure, just happy car finally made a few passes and didn't break lol) Futral motor sports dyno tune.
Future Plans to engine. Futral cam (F-13 or F-14) and heads to match set up.

 

My car ran 11.190 @ 119.75 with a 1.53(shooting for 1.4xx on the T brake). Kinda guilty with a 242/242 cam and ported 853 heads. I put down 445/429 before the 90/90 and TSP duals. I have a 4400 Vig convertor and 3.73 gears. The only problems I have are on my first start of the day. After that it's smooth sailing. This is my weekend/track car only since I DD the C5 and have a truck for winter, so I let alot of things slide on the T/A. The gas mileage is aroun 260 on the highway and sucks around town. Would mind having better driveability. It hauls from the start to the 1/8, but doesn't have the 121+ mph that I would like. It's seen 120 2 times though in less than ideal air(63+degrees, positive DA). I can't wait to run it this fall/winter. I want a 10.9 @ 120 by the end of the year, but we'll see. I'm not keeping this set-up anyways

60: 1.537
1/8: 7.081 @ 96.19
1/4: 11.190 @ 119.79

 

My car has run 11.364/119.5mpgh at a race weight of 3575lb with a small baby cam. Its a 216 220 114LSA with 1.8 YT RR, Ported Heads 10.7:1, Mamo Fast 90mm, OTR, 1"7/8 4 into 1 Long Tubes, QTECs, SS3600, 3.73s on MT ET drag radials 235/60 x 15. Its best 60 footer has been 1.551. I believe that this winter with recent mods a 4200 stall and 4.11s with a built 4:65e run 11.0/122.

 

what it the z06 cam numbers?

 

Found one that said stock LS6 cam is 204/218 .555"/.551" 117.5 lsa.
Summit sells one listed as "2002" to be 204/218 .550"/.550" 117.5 lsa. It's actually printed in the catalog as a reverse split but the website shows this to be correct.

 

Found this on Smokemup.com but don't know how accurate it is.

2001 LS6 cam
207/217 int/exh @ 0.05" duration
0.525" / 0.525" int/exh lift
116 LSA

2002+ LS6 cam
204/218 int/exh @ 0.05" duration
0.551" / 0.547" int/exh lift
117 LSA

 

I've been away from the board for a long time but I was surprised at all the large 230+ sized cams for stock cube 346's that seem to be showing up. Several years ago when we did my heads and cam car a 224 was a medium cam and now it sounds like it's considered small.

My T/A is one of the older Heads and Cam cars on the board. I don't have ET's to share because my T/A has ended up having to be a driver. I can't afford to break stuff currently so I don't get to race at the track. I still get to play around on the street and have fun with the car.

I'd planned for the T/A to be a weekend car only but able to be a daily driver if needed. We have five cars, so I was pretty sure the T/A would never have to be a daily driver. I was so wrong about that...

The soon to be ex-wife wrecked her Z-28 twice, the old daily beater RS ended up not being my daily driver for a long time. Later, the RS had a serious mishap and I ended up driving the T/A for two years as my daily driver.

In short, my heads and cam car has 93,000+ miles on it. I'm not convinced many of the big cam'd highly stressed engines will live to 100,000. I'm pretty sure the 224 sized cam cars will live past 100,000 with proper care even with seeing some serious street/strip use. Getting 28mpg highway with heads, cam & 4.10 gears is pretty nice too. Average is around 21 to 22mpg. Before the package average was 23.5 mpg with a best highway of 32.8mpg.

I really like to see one of these 230+ cammed cars, follow my car, creeping up a five story parking deck at 2mph. That's about the harshest test for driveability I've experienced.

With good planning and the newest heads, I really think there isn't a need for the "BiG CaM" for most cars. If the only driving the car sees is at the track then of course go all out.

I'm very happy with the set up.

A big cam would have been a disaster for me.

 

Small cams- you guys are gonna laugh at me, but here goes. In my truck with a 5.3 Im eyeballin' something along the lines of 200* 208* .502 .502. 115 LSA, Torque and power under the curve is what I'm after- if there's something better out there I'm all ears. I hang out at performance trucks and the cams these guys are running make me cringe- they all need a hi- stall converter and bigger trans cooler. All something I'll leave for the other guy. If I could cind a smaller cam that the afomentioned I'd go with it- something with like 195* duration, anyone have a source where I can find mellow/ small cams, or some listings of stock peices. I just forked out for HP tuners so I'm ready to rodeo.
any suggestions/ advice much appreciated..........

 

My buddy is in the same boat, wanting a cam for his 5.3. I was looking at two Comp grinds for him: 212/218 .522"/0.529" 114 lsa Xtreme RPM cam. Then a 208/212 .554"/.558" 115 lsa Xtreme Fuel Injected cam. I think the latter might be better for him, more lift and less duration. However, someone on Performance Trucks suggested getting it on a 112. Someone else suggested I forget the 6.0 cam I had in the 5.3, which was the original thought since I had one laying around.

 

BTW, I think the 5.3 cam is 190/191 .466"/457" 114 lsa and the 6.0 cam is 197/198 .478" 115 lsa. That's what I found anyway. 6.0 cam is 2001 2002 LS1 cam too.

 

I've seen the factory cams, and just wanted a small step up, want to retain the stock Torque Converter and such. Wow- I did not know that the 6.0 truck 197/198 .478" 115 lsa. Kinda impressive what they did with such a conservative cam, though. I'm shying away from excessive duration because of the weight of the truck, and I tota a 600lb quad or 2 once inawhile. From the looks of it- doesn't look like it would be worthwhile to swap to the 6.0 cam. I'm gonna do an HP tune and go from there..........

Edit: was that the Camaro LS1 cam or all LS1s across the board. I thought I saw that the 2000 Corvette LS1 cam was 198* 207* .500- .500......

 

Well the previous years' LS1s had more aggressive cams so those numbers you have for 2000 are probably correct. I think those two cams should be fine for stock tq converter in the 5.3. One of the sponsors commented that the 208/212 that I mentioned was a great DD cam/stock converter. He said get it on a 112 though and the torque will be right where you want it.

 

Yeah- that's just what I was thinking, the LSA at 112. That sounds like a Comp Cam- anyhow, I'm probably thinking old school, aka- 1990 L98 era. I guess These LSx's are entirely different beasts..........

 

Yeah Comp grind. These LS motors have a lot more potential in them than the older stuff.

 

Hi mate a guy here in OZ has run the specs for this cam through the comp cams simulators and they show very good gains right through the rev range.

63-LS-206/212 Comp Cams LS1 Camshaft - 206 / 212 .515 / .522 112 LSA 800-5800 RPM Power Band. Excellent low-end power. Mild Camshaft great for automatic cars with the stock or mild aftermarket torque converter and daily drivers . This cam won't stress your valvetrain but will return good HP and driveablilty.

I have just put a 212 - 218 558,563 @115 in my 6.0L and I have to say it's very impressive . The small cams make great power up to a sensible red line. A big cam will get big power up high but who wants to run around all day @ 6500 !!!
I found the small cam doesn't push on the convertor and will idle at 550 rpm !!! and still makes over 400 rwhp.

It seems to me that a lot of guys pick a cam that is a bit bigger than the last guy did on whatever internet forum you look at. IMHO dick waving doesn't cut it when speccing a daily driver it has to do what you want it do first and foremost.

cheers

 

Thanks, Enforcer. I guess these LSx engines are pretty flexible when it comes to camshafts and like something in the .520- .551 lift area. Hmm, guess I hafta rethink everything I thought about camshafts..........

 

WOW, this thread took awhile to read through. I am one of these old schoolers that back in 01 when I took delivery of my SS, mods for GEN 3's were new to the market and the 22x cams were considered big cams. I still boat with my original setup that I installes back in 01. A Thunder 224/114 cam, TTS headers(do they even make these anymore?LOL), Jay's absolute speed 5.3 heads(he's no longer around, most newbes have no idea how good these heads really are) and a ls6 intake. With some great tuning over the many years, I have sqeezed 431/411 at the wheels. I have almost stepped up and purchase a larger cam, but the TR224, in my opinion, is the most "off the shelf" proven cam in all catigories. Only thing I may do in the future is install a ported FAST and gain that last little few pony's.

I have to agree with the early posts, its sad that the market for proven small cams are going, but like you guys said, tuning has really changed everything.

 

I can honestly say that this thread has had me want to do just a heads cam LS1 motor rather than my 80mm turbo. However, I think once I get it going, it'll be fun too.

 

Great read. I am definitely going to go with a mild cam in my car for drivablity. I want the car to start up like stock, idle somewhat like stock, and have good tq for daily driving.

I'm going to be buying a cam within the next week and I'm still undecided on what to get. At the same time I install the cam, I will also do ls6 intake, ported TB, LT headers with a bullet in the I pipe and electric cutout in my borla for a quieter exhaust, and a 25% crank pulley. Stock heads.

The biggest cam I want to go with is a TR 224 114.

My question is this, would it be worth it for me to go with a TR 220 114 or the comp cam 212 - 218 558,563 @115 talked about above to retain more drivable for daily driving. I'm not worried about peak h.p. numbers I just want to retain the great street manners of my car that I love.

Anybody have feedback about the comp 212 - 218 558,563 @115?

 

Huge fan of my TR224 112. I did a lot of research before making my final decision as this car is a TRUE daily driver. Not having any other vehicles ment this car needs to behave under all circumstances.

I am very happy with the choice that I made. I was able to do the tuning myself and the car starts/idles/drives like stock, until you nail the go pedal. Very mild but good performing cam.
