Title pretty well says it. I know neither cam is large, but will the CC 216/220 give me quite a bit more performance than the stock LS6 cam? Thanks!

Hello C5XTASY;

Before I bought my cam I spent hours pouring over specs till my eyes crossed. I wanted a cam that closely mirrored the GM Hot Cam with a more idle friendly 114 LSA. I knew I would leave some horsepower on the table, but I want the valvetrain to last for years of reliable driving.

I called several cam tech lines and talked to their people. The nicest and most helpful guys were the techs from Lunati and Comp Cams.

I had a long conversation with Andrew, a Comp Cams tech. With his help, I finally chose a cam. Andrew stated that I should see 25 to 30 horse more than stock. So now you can compare your specs to mine below.

P.S. No, the cam isn't installed yet. I'm waiting on a friggin' backordered pulley before I start!

It will give more, but not "quite a bit more " depending upon how you define that.

You don't list any other mods. If you are are staying with the stock exhaust manifolds I'd increase your exhaust duration to 224.

Oh, and get a torque converter.

Actually you would feel a verter swap better than you would a cam swap.
Get the verter first.
Like a 3200>3500 stall

I'll be installing 2003 LS6 heads, an LS6 intake manifold, LS6 fuel injectors, Dynatech longtube headers w/high flow cats and X-pipe and a Vararam cold air intake, along with the cam. An LS1 Edit will also be performed on the car. The car is an A4 with 3.15 gears. Any ideas as to where it might end up with the 216/220? Thanks!

I'm not sure exactly what it'll dyno, but I can guarantee your definately going to feel a huge gain with a stall with those mods too, you might as well do it. My guess is 355-365rwhp through an a4 and the vettes IRS. I'd go ahead and do a ported throttlebody and pulley too while your there.

Peace,

I have a 2004 LS1 with LTs, 216/220 cam, AFR205 heads, and ASP pulley. I got 397.95rwhp SAE on a 2004 GTO IRS and AFR205s are suppose to be around 15 to 20rwhp over LS6 heads.

Is that with an automatic?

Here's the specs on the 54-414-11, XR269HR, 216/220 Comp Cam:
These are the specs:
XR269HR
Gross Lift:
0.525 0.532

Duration @.006:
269 273

Duration @.05:
216 220

Lobe Lift (@.05)
.309 .313

LSA:
114

Advance:
2 degrees

Interestingly enough, it appears that the exhaust specs on the 216/220 have been moved to the intake specs on the 220/224, and the 220/224 exhaust specs increased a like amount. I wonder how much performance, idle, drivability, reliability and mileage are all affected?

The effective range of the 216/220 was gievn to me by Comp Cams as 1300rpm to 6300rpm. What is the range on the 220/224?

The 220/224 isn't listed on the general LS1/LS6 cam listings on their website. I sure would be interested in hearing if anyone here is running this cam.

I'm trying to come to a decision here this weekend, and now you've thrown in another glitch for me to think about.
