T-rex in a 04 z06 question
You guys are sitting here arguing weight and gearing, etc. There's about a 200 lbs difference between the F-body and Y-body, depending on model, etc, which really doesn't make a big cam any more drivable. The M-12 vs the M-6? Once again. Not a big difference. Sure, the transmission has lower gears, but it's still not enough when you're talking about 3.42 gears and having to lug the car around light to light.
The fact of the matter is that I had a much smaller cam than the T-rex in my Corvette with 4.10 gears and I didn't want to daily-drive it. There's no low end in a big *** cam like that in a 346. Peak torque comes in way late and unless you roll around on ET Street Radials or something like that, light to light racing isn't much fun when you have to rev the car pretty high to launch it.
Period.

Last I checked, most C5s weigh anywhere from 32xx-33xx lbs and Z06s in the high 31xx. F-bodies typically weigh around 34xx-35xx lbs.
Regardless, it's not like you're talking about 500-1000 lbs.

You can make all the peak numbers in the world, but without a proper setup between compression, port velocity etc. you wont have the most desirable powerband. Not everyones setup is the same, so trying to compare his setup based off of your old setup and YOUR opinion isn't saying/doing much.

Also, what you fail to realize is that the LS6 has higher static AND dynamic compression than an LS1. Regardless of it being a half of a point in static, it still makes a difference. I could honestly care less what you had in your corvette. 1. it didnt have an m-12 tranny 2. it's heavier than a z06 and finally 3. your setup probably wasn't matched too well.

blackls6, If I were you, I would call Thunder and ask to talk to Geoff. He would be happy to talk to you about this topic. And would probably tell you that you would have better results in that car with a Trak cam since you are planning on keeping the stock gears.

blackls6 dont listen to a guy who makes uneducated posts like this. It cant be good for you or your car.
blackls6.. do what stl2slo said and just call thunder, ask for Geoff or shane and listen to what they have to say. I just got off the phone with them because I had to order a couple things and figured I would ask about yours. As soon as I brought it up the guy I was talking to chuckled and said "you must be referring to the thread on LS1tech." Furthermore, they said even though your Z06 weighs less and it's true that you have a stronger first gear, they recommend a 4.10 gear minimum.
In the end, it's your car..you do what you want. I had a good sized cam in my camaro before the T Rex and even with that one I needed 4.10s. Previously I've had a couple C5's and two of my friends have Z06's so I'm telling you from the perspective of having the exact cam you want...stock gears aren't going to do it for you...Z06 or not.

and I don't know where 550 hp is coming from with h/c..i'm assuming he's talking about 550 flywheel because if there is a h/c combo out there thats landing you that much to the wheels on an LS1 I'd like to see it. not that it matters a damn but mine put those #'s down on a mustang dyno so even on a dynojet that would only be what..20 horses more? hell i'm doing a 408 and i'm hoping just to hit 520 or so lol

Some things you just have to spell-out for some people.

You don't know WHAT THE **** you're talking about, guy. I've had more LS1 cars than you've had pairs of Fruit of the Loom underwear your grandma gives you for Christmas.
I had a 4.10 geared C5 6-speed with a 236/239 .600/.611 cam that was NOT fun to daily-drive. The thread-starter wanted to know if a cam BIGGER than the one I had would drive well with the stock gears behind a M12.
The answer is:
NO
Period.
I don't give a **** about how badass or cool you think you are. :shrug: I don't give a **** that you throw around slang like Static Compression Ratio or Dynamic Compression ratio, more SCR/DCR with the LS6 Motor vs the LS1 motor, 300 lbs weight differences, etc, etc, etc. Anyone like you can use the search button and copy/paste what someone else has said. Not impressive.
Honestly, you really need to do more suspension mods to your car and leave the motor more stock than it already is before you can be man enough to change the blinker fluid or muffler bearings.
Your cronies think you're funny? Keep them in your circle and delude them with your advice.
I'm done with this thread. No need to keep bashing for no reason.
