ZO6 Heads and Cam?
ZO6 Heads and Cam? I want more power but I dont wnat to use and after market cam with a 110 or 112 lobe seperation. I heard the cars gas milage goes down big time. I'm thinking the Z06 set up is the way to go. You still get great gas milage and 405 hp. I was wondering if a stock LS1 can handle the RPM's a ZO6 cam will give me. I think most guys shift there ZO6 at 6,700 RPMs. What do you guys think?
Thanks
Thanks

Re: ZO6 Heads and Cam? upgrade your rod bolts, or start shopping for a short block.
Don't be squeamish about aftermarket. Cams are cams. Just cuz GM slammed it in a car doesn't make it perfect. In my opinion, they just aren't aggressive enough. The idea of replacing a STOCK cam with another STOCK cam sounds kinda silly to me..

Re: ZO6 Heads and Cam? I think by the time you drop $2000 for LS6 heads and cam, you could have twice the power using some quality heads of your choice (over there>>>) and a mild cam. You don't have to go down to 110 or 112 LSA to make huge power. FWIW, I get around 24 mpg with my setup.
Re: ZO6 Heads and Cam? upside to the LS6 setup is awesome top end, perfect drivability and no tuning required... downside is the torque numbers I made were kinda weak... so stock cam came out and now G5X2 is going in with the LS6 heads to see how they work
Re: ZO6 Heads and Cam? Why do I need to upgrade rod bolts. I know a lot of guys buzzing 6,800 rpms with 500 passes and no problems. Any info will be appreciated.

I hope I made my point and if I haven't drop me a note and I will explain it like I do to my three year old.

Re: ZO6 Heads and Cam? ive been considering going this route since im already halfway there.thing is these heads arent exactly cheap at over $700 a piece.they will make considerably more power than stock and are very streetable and legal
however there is better heads out there priced comparably that make alot more power.no matter what heads you go with youll need tuning to get maximum power.im leaning towards getting these heads but thats just me.if youre looking for serious power id look elsewhere.

Verdad Gallardo Re: ZO6 Heads and Cam? I want the power and the fuel economy so these heads are the way to go. A Z06 get 29mpg with a 6 speed. I've heard horror stories about TEA and other heads that flow better. The gas milage can drop to 16mpg really quick when you combine a after market cam with a 110 to 114 lobe seperation. 114 being the better for fuel milage. The stock cam and the Z06 cam have a 117.5 or 118 lobe seperation and there is less overlap where both valves are open. This equates to raw fuel excaping through the exhaust valve and the crappy gas milage.
Re: ZO6 Heads and Cam? 16 mpg?????? I just logged 27 mpg on my last tank. That's with about half city and half highway. I have a 112 lsa cam. I've never heard ANY mpg issues with ANY aftermarket heads or cam.

Re: ZO6 Heads and Cam? well, your mileage WILL suffer a bit the more aggressive you go with H/C. Not as much as stated above (6 - 9 mpg), but it will change. I've seen a few examples of this from others.
also, .........I don't understand why some people feel the need to ridicule the ZO6 package. What's the point in that ? everyone has their own idea of what they want to do to their car. Some people are happy with a low 12 second car that's just as reliable as stock, emissions legal, smooth idle, with no tuning issues. Others won't be happy until they run 8's, even if it means blowing their car up to bits. Everyone has their own goals.
One of my friends got himself stageII MMS heads with 228, 571 112LSA cam. Sure he'll make more power than me with my ZO6 upgrade, but he also spent well over twice as much as I did.
so, are you happy with an 11 second car, when a 10 second car will be waiting for YOU at the finish line ??
it's all relative. There will always be someone faster than you.
and if all I cared about was HP / dollar, then I would have simply gotten NOS.

Re: ZO6 Heads and Cam? With traction a Z06 can run mid 11's. I've seen lots of bolt on cars run 12.0 in the quarter so I assume that if I get my car down to 12.1 with bolt on and header the Zo6 package should drop me down to 11.6.
Also, what kind of RPM's does the Z06 tach. At what point should I shift.
Thanks a lot guys for the input . Keep it coming.

Re: ZO6 Heads and Cam? The ported LS1 heads will make more power than the stock Z06 heads and enable you to run a milder cam to make the same power as you would with the Z06 heads and a larger cam. Since fuel economy is a primary concern, the LS6 cam is a good choice. Match it up with some high velocity, good flowing ports and you'll make lots of torque, have great response, and maintain fuel economy.
The cam selection has more to do with fuel economy than anything else. Also, the extra compression from the milled heads will actually help fuel economy.
