This is only the first cam in this motor and we will be changing in a week or two to the next cam size. We are doing this to achieve what we really want out of this motor and to grab the best of both world. Now, the best part is this also helps everyone else out there trying to understand the new L92/L76 head and intake combo. So here it is. A break down of the car first. AND No its not Flywheel power.
99 f-body.
iron 408
11.5 CR
L92 heads, touched up exhaust.
L76 intake with UMI 90mm TB.
American Racing 1 7/8th long tubes with no cats.
Corsa catback with extra magnaflow muffler in the I-pipe for sound reasons.
42lb injectors
Ford 9inch
3.5" driveshaft.
6-speed car.
Mcloud twin disc.
This should cover most of what you need.
I am going to give out cam specs today to help other understand how simple and tame this combo is.
Cam specs. 230/242 116+2 LSA .590/.578
Customers goals where simple, TQ all the time, and fun to drive. I will admit, I wanted more powerband, but thats the great thing about trial and error, so the next cam will fit the bill even more. Enjoy.

Very nice for a cam on a 116+2!
I see you must be getting older than most in here, Corsa exhaust plus and inline magnaflow to keep the noise down on top of the cam being on a 116 for nice smooth idle. I hope that does not get lost in the discussion at hand on power output.

that is the equivelant to a stock cam in an Ls1... tame LSA.... very little lift. just a bit of duration...
man you need to go bigger!!!! you are losing at least 30-40 horses with that tame cam.

I figure whatever i lose in the final configuration (factory muffler & inline bullet) is a simple "jet change" away

exactly WHO do i need to go bigger for? if anyone wants to see what this thing will do with an "internet inspired" cam..... SEND ME SOME MONEY for labor,parts, and dynotime

Seriously though who should i install a bigger cam for?
we ARE going a TAD bigger (and i mean tad!) but not because im unhappy with the power...... more so that the cam thats about to go in was/is actually spec'd to what I WANT (as opposed to puting an on the shelf grind in there.) in plain english this cam (current) got me to about 96-97% of where i wanted to be.....im almost CERTAIN that the new cam will get me the rest of the way there: IF i get a few more rwhp out of it that'll be a plus: but not what im ultimatley looking for.
The car is FUN to drive which is what i was going for.... I had/have no intentions on being the biggest baddest L92/L76 408 owner on the internet....
i just thought i'd SHARE my real world experience with you guys... i wasn't asking for suggestions on how to make a number that the internet would be happy with

that would be a mean street crusier. the HP/TQ is just about the same and not to far apart from eachother would just allow you to rape alot of htings on hte road and seem perfectly stock. also lets think there is so much more to be made if someoen wants to push the enevelope

I congradulate you and I understand how you feel about just wanting a really fun car on the street. You have ~500 rwhp and ~500 rwtq. Combine those with the 3.70s and that car is probably fun as hell driving around without having to shift too much. I know I hated having the 4.10s, and switched to 3.73s, but I wish I had more torque at 2000rpm. I know you don't have that problem with the amount of torque your putting down.
Congrats. Drive it like you stole it and have fun. 500/500 at the wheels must be fun as hell. I'd rather have that then 550hp/450tq.
