So I know there's a ton of these. But I can't find one close enough to my car. So my question is. I daily a 2000 WS6. Bone stock. But I am going to do a Cam and Gears.
I want to figure out what the biggest cam I can get without ruining the drivability of the car?
I'm thinking .550-.600 lift. Is that too big? Anyone daily one of these with a "big" cam?

Thanks in advance

 

It's not the the lift it's the the overlap that will cause drivability issues. What trans do you have?

 

Check out our HIGH LIFT HOT CAM

It sounds great at idle, easy to daily drive, easy amd quiet on the valvetrain and a good price also!

Video link and dyno graph in the link!!

Works great with any gear also.

 

A good tuner can make a "big" cam have good street manners.

 

Well we just got word back and our new high lift hotcam gained 4mph over the orig gm hotcam.
So maybe that helps cement some cam plans.

 

The original Hot Cam gains 65HP on an otherwise stock LS3, over the original 430.(The GM Crate engine is called a 480, but is acknowledged to put out 495HP) where do you think power would end up with your cam on the same LS3? I think the LS3's heads would devour the extra lift your cam has and increase HP by somewhat more than the 10HP gained on smaller engines like the LS6. I could be wrong.....

 

Id hope for 500 at least vs the gm 480. I do not like to speculate on that really though.

 

And here is the thread

Looks like 5mph...pretty good imo

 

Even 10 over the 495 I stated would be 505, and if you think it would be over 500 vs. the 480 commonly held, that is over 20HP gain. Hey, all speculation, but when you gain 5mph, the gain can be calculated, though I haven't a clue how lol.

 

I know this is very vague to answer but an idea on rwhp and torque please.....
So on a stock ls1, with an ls6 intake, BBk 1-3/4 headers, BBk 2.5 y pipe and stock exhaust out the rear, through a 6 spd with that high lift hot cam, what do you think it will put down?
How bad will I need a tune after install?

 

I think based off the orig dyno you can expect at least 385/365. likely more.

Youll need a tune but you can drive it to the tuner as long as its within an hour id say.

 

A 224/228 cam would be perfect

 

I daily a 237/245-112.5+2, lift is .653/.638. It's really not that bad, although trying to hold 15mph is tough. Once I get over 1500 rpm, it's fine. I can cruise in 6th at 60 mph with no issue. Gear always helps, because you get out of the lower rpm sooner.

^yes^. I lucked out and had a great tuner, but I still ended up getting HP tuners to make fine tune adjustments as time wore on and I found little issues I wanted to fix.

What makes a cam tough to tune isn't lift, and it isn't duration. it's overlap - when both valves are open at the same time. overlap is power, because the exhaust vacuum waves jump-start cylinder fill. However, overlap is also a vacuum leak AT THE VALVES. So, basically you're driving around with random vacuum leaks and misfires at low RPM. You can make a big cam very tame and a small cam a real pain in the *** with overlap.

Examples:
**230/236-116+4. 0.625/0.610 lift. Has 1 degree of overlap. Would have an idle note, but would not be all lumpy and would be very pleasant to drive. Now, you'd need to mill your heads to regain dynamic compression if you wanted good low end grunt, but this cam would be relatively tame

**224/230-108+0. 0.525/0.525 lift. Has ELEVEN degrees overlap, and would really test your tuning skills without making much power up top to compensate. Edit - so, you see a small cam can be made to be a pain, and a big cam can be made mild. overlap is the key ingredient to engine "behavior" at low RPM. not duration or lift.

Now, if you're going to cam and then gear down, which honestly, the two do go together quite well, then you can err on the side of being larger, and as long as your overlap doesn't get crazy, you'd be happy. Honestly, the hypothetical 230/236-116+4 i threw out randomly might not be too bad. probably a little more realistic would be something like 227/231-114+2, which would have decent torque, decent manners, and not choke off at high RPM.

So, consider 227/237-114+2 my recommendation for a balanced cam shaft.

 

I have 224/228 112 and it would be the max I would go for a daily driver...my car is just a weekend garage queen. The 112 chops pretty good, the 114 lsa would be better if you want a smoother idle. For a true daily driver I would opt for something smaller like the WS6 store Hot Cam or 220r. For a weekend only car something along a 228r would be ok too, the 224/228 is kind of a balance between the two.

Age makes a difference...when I was 18 I probably would of daily drove a MS3. Now that I am 36, the 224/228 112 is right at my limits for what I consider daily driver friendly in a 346.

 

What does this run without the springs? Any idle sound clips?

thanks!

 

Click the link it has a link to the video. cam is $389 by itself.

 

I run a 228/228R cam with a 6 speed and I drive it all the time! Once the AC goes it in, I will DD it.

 

I had a 230/232 cam a long time ago. I liked it as a daily.
Lots of torque and horsepower and it had amazing throttle response.

 

Interesting to hear. I have been looking at the Torquer V2 as a daily which is a fair bit more aggressive than your cam... I would have considered the 224/228 to be pretty mild. Good to know

 

What is tame enough to daily depends on what you're willing to live with and how good you can tune driveability which I would recommend learning how to scan and tune your own car.

Generally speaking, on a stock cube LS1 with stock gears using the standard off the shelf cams, I would limit the intake to 228 and go up to 232 with gears. You will gain power up top with more duration but if you aren't geared to use it, it won't be near as much fun. Torque is fun on a street car. Yes Vader gets into some good more detailed points.

I ran my old 228/230 112+4 on 3.42s daily and would do it again. It did love 3.73s. A close friend has the CamMotion Titan 4 on a 227/232 113+4 on 3.42s and it runs very good as well. The F11 was a CamMotion ground cam as well.
