I am going to be running 9:5 to 1 compression on a Forged 346 LS6 motor (which i am going to start having built in the near future) for my 02 Z06, powered by my ECS D1SC Procharger kit, which is a street car and will see between 8 to 14 lbs of boost at any given time on the street and occassional track day (both roadracing and a little drag racing). Also, important to note that i am going to be running my new forged set-up with my 100% stock LS6 head (except for valve train upgrades for the new cam).

I want a fairly agressive cam without going to big, which will make great power off the boost and on the boost of course, and am thinking of something like a 226/232 cam on a 114lsa, with a .588 lift. or 224/230, 114, .588 lift.

What cam do you EXPERTS here recommend for me for the my custom CAM specs for the use of my car as described here.

I certainly don't mind running a little bit more of an aggressive cam similar to the specs set forth above, but don't want to overdo it as my 02 Z06 is primarily a street car, but would like to have a nice midrange HP increase when i am not seeing boost and running the car between 2000 to 3000 rpm, etc., but of course most importantly, I need the cam to perform like a champ when seeing anywhere between 8 to 14 lbs of boost at any give time!

THANKS you guys are GREAT!!!

OK, I willl start it off-Just got this from SLOHAWK and am really digging it:

224/230, 114lsa with a valetrain friendly .575 lift.

Don't all chime in at the same time!! Or has SLOHAWK nailed this one right on with no questions asked? TTT

I am going to get my engine forged here soon for my ATI Procharger with about 14lbs of boost. I will be runnning the LPE GT2-3 cam because it makes good numbers and has good street manners.

Stock camshaft will work great. Spend your money elsewhere. sell those ls6 heads ($5-600) and buy some Dart or PRC ported heads for $1k with stock ls6 springs.

Then youll save not buying valvesprings, pushrods, camshaft and put the $500 from your ls6 heads into good heads. It'll cost the same amount and make alot more power.

If you are going turbo I would stick with the stock 02+ Ls6 cam.

actually thats not entirely true,youre still going to want to do pushrods and springs as well because of the extra pressure especially on the springs trying to push the valves closed when boost is trying to push them open.many stock guys that dont do springs end up with valve float...then post on here asking why,then swap to comp 918's or something similar and the problem goes away.

Why so much compression?

Z06 Cam here see sig. Conservative street tune.

Keep your cam, spend the money elsewhere. The Z06 cam works great in FI applications.

I would stick with the stock cam, if you're trying to acheive an F.I. setup for the best possible money.

Unless specific cam specs. are given, the cam Slowhawk is recommending will likely optimize your supercharger setup and give you a distinct power advantage that is matched to your setup. You may see an additional 20-40 rwhp under boost versus a stock cam.

edit: sorry, said turbo, meant Supercharger...

CHRISPY

Ditto,

If you are running pump gas I would go lower on the comp.

I'd also use your stock 02 and up LS6 cam and swap in hardened pushrods and PRC double springs or Comp 921's.

60# injectors and proper pump setup.

Guys, I am running a East Coast Supercharger Procharged D1SC set-up on my 02 Z06 ((not a turbo) which is driven 99% of the time of the street. The 9.5 compression is perfect per the research i have done with tuners such as SLOWHAWK, etc., for the use and power goals of my car which is 700 to 750 rwhp at 12 to 14 lbs of boost MAX with my new forged motor set-up (utilizing my stock lS6 heads).

I am not going to a turbo set-up as my ECS D1SC kit has been very reliable on my stock LS6 motor and makes more than enuff power than i will ever be able to hook up on the street. Keeping the stock Z06 cam does make sense for sure from an econmoic and realistic perspective as it does make an excellent blower friendly cam and i have already recently swapped to brand new 918 springs and manly chromoly pushrods on my stock LS6 heads which i am going to keep using on my forged shortblock which i am going to start having built in the immediate future. If i use my stock cam i am good to go and don't have to touch my valvetrain but i would really like a BIGGER more AGGRESSIVE cam that will make more power than the stock Z06 cam on and off the boost. Unfortutnaly, I will have to throw more money for new PRC or comp 921 springs if i upgrade to the bigger cam but oh well, if your going to play you have to pay!!

I agree with you guys 100%, that if i was running a TURBO or planning to get away from my AT1 D1SC cent. supercharger (which i am not) and was looking to make between 14 and 20lbs of boost, then I would be going with a lower compression motor around 8:3 t 1 etc.!

FOR MY set-up desribed in this thread, keep the CAM SUGGESTIONS COMING including your votes to keep my stock LS6 cam in the new forged shortblock! ALSO, CAN SOMEBODY PLEASE POST the SPECS of a Z06 CAM as i have forgotten them?

ive heard nothing but good things about that cam

I would have to completely disagree from doing a million cam swaps and dyno tunes... If this were a stock LS1 spring I could agree with you.

Stock LS6 springs and pushrods are more than enough for the stock 02 LS6 camshaft. The added boost is going to make no difference and isn't going to push the valve open. Stock springs are the most reliable and wont wear out.
Dont waste the money.

Also....I dont understand you need to keep the stock LS6 heads. Doesnt serve the right purpose here. Run the stock Z06 cam and save your self $400, sell your LS6 heads (keep your springs/pushrods) for $500 that total right there is $900 in your pocket

Buy PRC CNC ported LS6 heads for $900 and itll make MUCH MORE horsepower gain than just putting in a aggressive camshaft and leaving the stock ls6 heads, have better driveability, economy etc and you can still keep your compression at 9.5:1 if thats what you want.


Going to PRC LS6 heads will be a complete wash in price vs keeping stock ls6 heads and a big cam. The CNC ported heads will make alot more power on your car under boost that putting in a bigger cam with the stock heads. It'll also help keep boost psi down and should let you get away with a little more boost on pump gas.

I ran stock Z06 cam, pushrods and springs all last year...

Now I have 918s (or similar, whatever comes on the dart heads), stock pushrods, same z06 cam and 9.5:1 compression and it seems to run OK. I dont run 93 at the track but with only 16 degrees of timing or so I'm sure I could if I really wanted to, I drive the car all the time on pump gas (and show it little mercy on the street) and havent blowed it up yet

i missed where u said in the first paragraph about getting heads with ls6 springs already on them.....i would mostly agree that they would be ok,depending on the ammount of boost.im not sure if the million cam swaps youve done were on boosted apps or not but there have been plenty of people whove had stock cams and springs and pushrods add an STS kit for example and cant rev past 5k-5500 for some odd reason,as soon as they swap springs problem is solved,maybe you could explain to me what the difference was?it doesnt matter anyways cause he has springs so he doesnt have to worry

SO does everyone agree I would make more power between 12 to 14 lbs of boost if I keep my stock Z06 cam and upgrade only my heads instead as suggested above in my new shortblock application vs swapping out to a cam with specs of 224/230, .575 lift on a 114lsa (+0 advance) and keeping my stock LS6 heads? If that is the general consensus, then that will change my line of thinking and i will concerntrate on Patriot Heads ported LS6 heads and just keep my stock Z06 cam.

Also, to the gentleman running 9s with his D1SC Blown F-body with the wheel to wheel shortblock making 9:5 to 1 compression, and ruuning a 01 Z06 cam, are your JE pistons dished at all and if yes how much, and what cc Darts heads are you running 72cc, 62cc, etc?

Your type of set-up is exactly what i am looking to do with my new D1SC shortblock, as your motor is making great reliable power and your trap speeds and ets are VERY IMPRESSIVE!!!

The 02 LS6 cam is considered great for boosted apps. You'll get a little more power with a blower cam, but frankly I don't think you'll have any trouble achieving your power goals with stock Z06 heads and cam. With the money you save on the heads/cam you can buy an 8 rib assembly.
