Yes I got it 
Unfortunately I am a bit of a div when it comes to engines so simpler the better
!
Another div question. What is the deal with the cam range quoting say for the RM13 1600 - 6800 rev range and the fact it can idle at far lower ?

For a lightweight vehicle like the Cobra, you'd be better off with a slightly larger cam. It wouldn't make as much low end torque (don't need it) but will make up the difference on the top end. You would also be interested in gearing the car and the cam/powerband to maximize the "thrust." You don't want to bog or sping the tires too easily from a standstill or slow corner.

The factory road racing cams have reasonable lift with a long duration.
I would not listen to "most" of the guys here, they have ZERO road racing experience, zero experience road racing an LS 427 and about 1 in 50 has a 427. The C5R (427) guys generally shift at 6,000-6,500. This why this combination is reliable, just don't need to shift any higher. The Caddy is running a destroked 331 and is shifting in the mid-7,000 range. They had all kinds of problems finishing last year.
On a two minute course, you "might" see a 0.1-0.5 second difference between shifting 6k of 6.5k depending on the straights. If your racing professionally you need every tenth and will be rebuilding your motor on a regular basis (and have five spares).

I wouldn't have someone port the heads that doesn't do a lot of work on lsx heads. They can do more damage than good if not done right. Why not just buy a h/c package from a sponsor over here. I think that just a F13 cam would get you were you want to be with heads. I tuned a car with one and idled at 850rpm nice and smooth. Ran 12.3 @ 109 mph so far with two loose distributor cables.
supercharge or turbo it, done deal and powers always there. plus you can run a mild cam and it will be easy to drive around town, and have tons of grunt down low to match the power up top.
depends on your budget for mods.
You have raced at The Ring???
That is a dream of mine.........someday before I'm 50 I will do laps at that monster!

10 Camaros You Should Never Buy
I addition to the cam and heads, do you have a good LS1/LS6 Tuner over there or are you going to be tuning the car through a computer program such as HP Tuners? If you dont have access to a good tuner and a dyno then its gonna be tough to get any cam running right unless you can talk to one of the sponsors and see if you could send them the ECU and have them tune it to the specifications of your modifications. Good luck with the project though, id go with a 230 intake/ 232 exhaust cam with the ported heads, that should make some real nice power!

I've got a div question too...... What's a dive?
And on a side note, I'm staying up to respect your 2 minutes of silence. I can't tell you how much we appreciate Great Britton.

edit::: o and when did he say this was going to be a track only car. I am not talking out of track experience i am talking out of daily driving real world expirience on 1.7 rockers u can run a larger more agresive cam, with better idle than a smaller cam on 1.8 rockers damn go drive around in the real world ok before u start trashing other plp on here. o and did i mention 1.8 WILL LIMIT UR AFTERMARKET CAM CHOISE ON A 346 BEACAUSE OF THe AGRESIVE AFTER MARKET CAM RAMP RATE!!!! go read before u trash. o and u did read the part where he said the car was gona be daily driven right?

o and yes i guess if u want to u can run 1.8 on any cam but thats like shooting ur self in the foot to get out of the army stuped, u will loose and kill potential, u will have more potential and room to work with if u stay on 1.7 and play with ur cam choises, as to an explenation to why see my last post. o and i cant say this enough an ls6 is nothing like an ls7 wich is a 427 nostly based on teh c6r engine wich was a full blown racing engine damn! but iam sure with all ur track experience u already knew that
