What size cam would you guys run on a Z06 build?
Is mid 220/mid 230 mid 620/mid 620 on a 115-116 LSA a good place to be on these cars? I am going over build and I think that would be a good place. I will never run nitrous on the car and will mostly be drag driven with limited tracking. I will run meth on the car to keep IAT down.
Thanks for thoughts.

No thoughts on cam specs? Is this like G14 classified or something?

I don't think any people have had their stock cams profiled. The only people that would currently be privy to that info are tuning shops as the aftermarket for the LT4 hasn't taken off. May be call TSP, Lingenfelter, or Vengance and see if they'll share that info (if they even have it) with you.

These cars don't need much cam to really perform.
I'd keep it in the low 220's on the intake. I've ran a 218 intake lobe before.
The exhaust can be bumped up to around 240 to really get all that air out.
You'll want to be careful with overlap and especially intake centerline.
Since you have a cam phaser, you can run a much more aggressive intake centerline, and have the cam more advanced than previous. Then use the phaser to retard the cam as RPM increases.
LSA will be a byproduct of the overlap and durations you chose.

I was thinking of the cam specs above for an aftermarket cam.

Thanks I was thinking of running like a 224 on intake and 236 on exhaust with a 115 LSA.

Where did you get the 115LSA? What ICL would you run?

Stock is 189/223 120LSA, which puts overlap at 0.050" at -34 degrees.
Yours is zero degrees at 0.050".

Is this for C7 Z06? where did you get that info from?

I am planning on running the cam straight up right now so 115 ICL and 115 LSA.

Maybe he put a stock cam on the cam doctor, would be my guess...

PRE-Z06

I'm gonna guess from when it was posted last August...

I run a 220-230-117 +4 in most of my LT1 engines and generally make just north of 700 RWHP on pump gas without trying.
I'm pretty sure this is exactly what I'll run in my Z (when I get it)

I wonder where he got those cam specs from He listed the cam we spec'd for him in his Z06 btw.

Why does it seem that nobody is taking advantage of the phaser?
Putting a cam straight up, or just a few degrees advanced. Seems to be a non-phaser type of thinking.
The phaser is great. Run a crap ton of advance and use the phaser to retard it for high RPM power.
Best of both worlds.

I did get the Z06 cam specs from the site listed above.


I'd run a 222/238 HR121+12 as a baby Z06 cam. Stock idle. Stealth type cam.
This would give more off boost torque low in the RPM's. And the phaser can account for all the advance put in, allowing a straight up centerline by redline.
If you want more aggressive, then lower the overlap and advance. Try to keep the ICL the same.

Haha dont be giving all my secrets away Joe, LOL!

Good thoughts on the phaser. Have not thought of that.
