Confused on Cam to use I have been searching and trying to educate myself on valve train on here so that I can buy a cam I can be happy with. The issue is that I am not buying this cam for track use, but for autocross/long drives on the autobahn. I am in the military and I am going to ship my 67 ls1 powered Camaro to germany.
I have a ported fast90/nw90 setup, with a stock 04 gto ls1. It does have hooker super comp LT with 3 inch exhaust hooked up with flowmaster super 44s. Its got a T56 that is hooked up with a currie made 9inch with a 3.90 trutrack limited slip diff.
Suspension is c6 based front with coilovers and 4 link with coil overs in the rear.
I have been reading and I want something streetable, yet be able to really open her up on the autobahn. I want to see I can get this car to do. This is not going to be my DD, I have a beater for the cold winters in germany. I was leaning towards the polluter because of the price for the packaged deal and the dyno is really impressive. I just recently heard of the "el toro" custom grind and I am liking what I read on that, dyno and track performanve. I would appreciate any suggestions and some direction to take to reach my goal.
Thanks guys,
~Tony

GORGEOUS car. I asume in the 3200lb range...Stock heads??? I am asking before the cam guys do...
For some other advice get your suspension setup to handle AB speeds which is totally opposite of a drag race suspension. A DR suspendion is downright dangerous in that enviroment...

Just about. Yea the heads are stock. Only things that have been changed is the custom exhaust and the intake/throttle body.
The suspension is custom made for that application. Fully adjustable coilovers on all 4 corners, 12.19 inch 4 piston brakes on all 4 corners as well.
Thanks.

El Torro cam or similar will do what you wish, and remain far more tractable at lower engine speeds (city driving, autocross). There is still enough duration there to push 6800-7000 rpms if needed. Avoid the temptation to go all out when selecting your cam and you car should be a hoot to drive.
Nice car! Hope you enjoy running down some euro iron on the AB.

Cool so to be clear "el torro" cam is 230/230 .612/.592 111+2 LSA is that 111 LSA for both lobe separation and intake centerline? What rod lengths would i need and is there anything else i should purchase with it?

lol not to sure about the last question, but I would get that el torro cam but instead of 111+2 lsa I'd go 111+3 or 112+2 to get the lsa up higher to move the powerband up a little to make use of the power on the AB, just something to think about. As someone else said that cam has enough duration to spin to 6800-7000 it would just be better for it to be set up to do that instead of pushing it to do that. My .02 cents

Yea that is why I posted the question, everything here seems to be about the quarter mile. No offense to that, but it is not my thing. I want something that has manners on the street but yet put a big smile on my face on the autobahn. Do you know anyone that I can ask about that?
First off, very cool car man!
It sounds like you want a mid size cam. One that is very streetable, and still makes some impressive peak HP. For you, it sounds like the Polluter might be a little bit big. The El Toro cam seems to be closer to your needs, but I think you would still be comfortable going a little bit bigger and make a little more power. A cam in the middle of the two you mentioned. I would say a mid 230's cam would really fit your needs perfectly.
Why don't you give a PM to Patrick G, or Predator Z. They can spec out a cam for exactly what you want. I see that you are a little bit new to this website, so if you didn't know, the 2 guys I mentioned are the pros at this.
Good luck man. I know you are going to enjoy that car.

No, but I suggest you choose someone who has done autocross-style LS cams. Preferably someone who also successfully autocrosses an LS engined car so they know what works.

Just pm old SStroker...... 
I have the El Torro cam and it is an awesome cam. Very very streetable but when you wanna rip on it, the power (lots of it) is there. The cam is very strong off idle but imo really shines from 3000rpm and up. Itll pull harder the more you rev it too, which i love. My car still hasnt been tuned except for some light tuning on the street so i can drive it but when i get it on the dyno and dial it in, ill post the results.
And +1 for talking to predator z or pat g.

Para67, if you plan to run this car at/over 250 kph on the AB, which I assume you will, you need to work on the aero to kill the lift. Stock Gen 1's have considerable aero lift at high speed. That gets exciting really quickly!
The stock Z28 decklid spoiler isn't bad and won't kill the look. If you want to add one on just for AB runs (on a scrap decklid, I suggest), a flat plate about 4 inches tall leaned back 15° or so might be good.
You also need to use a front air dam, preferably 3-1/2 to 4 inches high and as wide a possible, at least from inside-inside of tires. The kind used on the TransAm Camaros is ok, but a vertical one a little farther back should also work well.

Additionally rake the car (nose low, of course) at least 1°. That's a difference of about 1-1/4 inches in rocker panel height from just behind front wheel opening to front of rear wheel opening. The ground clearance in the pic is just about right...or a little lower. Get the airdam near the tarmac.
Again, I really like your car!

Cool, I really appreciate the input. I have the front air dam, it is not installed yet. I still have not gotten the rear deck lid spoiler. I will consider that. As far as the rake goes, and the front ground clearance, the car is not finished yet. It will have the car siting lower than it is right now. I will dial in the stance one I am home, before I ship it.
Thanks again for the advice
