415ci Cam options....
415ci Cam options.... I am getting closer to get my car on the road, and have been VERY patient in selecting items for it.
And yes here it is the CAM post.
I have done ALOT of research on past posts and read ALOT of the tech articles, and have called companies, and pretty much confused myself pretty good.
I had a vendor recommend this cam, which was interesting to me...
242/246 592/595 112
This car is not my DD, if you can get me out of it!
I dont have any real plans for road racing, or even strip racing.
I would like to get a strong pulling car from the 2400 to 6600 rpm range
This is what the motor is:
415ci
6.0 liter iron block
4.0625 bore
4.0 stroke
Valves 2.08 intake 1.60 exhaust
TEA stage 3 LS6 casting heads
.51 cometic gasket
Ls6 stock manifold
Chamber is approx 62-64 and should be in the 11.2-11.5 range
Heads flowed 350 cfm @ .600 lift and and are approx 239-240 cc intake runners
LG 1 3/4 headers, no cats
Manual 6
2002 Z06
By the way, I found that there was ALOT of reviews of common cams etc, for the 346ci motor size, but not many on the larger cube motors.
So I kept that into consideration when reading over alot of others opinions.
Looking for some help.......

I ran a Comp XE-R in my 408.
244/248 .612/.615 lift on a 115lsa
I made 470 to the tires through stock, untouched heads. Great all around power, amazing torque too. Granted this was on a stock headed 408 (not optimal by any means) but it made amazing power.

Jeb have you contacted FMS yet about cams? Either one of the cams I have had would work. The one with the best midrange was the 243/250 LSA 112 cam from FMS. Allan will not let you down when it comes to cams. Ask Jake with the red 03 Cobra that was spraying the hell out of me about our race when I first got back with the SS. He asked for the hit and I went right by him on motor like I was spraying... You can ask CBRTX about the first time I raced him in my FRC when he owned a Cobra that he sprayed how the first run he got ran down and the first words out of his mouth were you were coming up fast in my mirror. I also gave him the hit. My point is there is no problem with low end grunt on the FMS cams.. It is not easy to run down a root style blower car that is spraying when you are on motor..
Vince, Yes I called Futral, and also emailed them my situation, and am waiting for their response.
So from what I have gathered
24x 24x 59x 60x 112lsa is prety much where I need to be.
I would like to have some more opinions and insight before I make my purchase. I would hate in 2 months to have someone say," Oh no you should have gone with......." or "thats too small for what you need"
Anyone have other advice?

Well you have another option.... If you have the exact head flow #'s you can contact Cam Motion and they will provide you with the exact cam you need for your driving....

jed I have done a few 408s in the last few weeks with 248/254s around 62x to 650s ish lift 114 LSA in them and excellent drivability. Thats just my opinion. But I believe that we can get it right on and make plenty of power as well. These other cams recommended are going to make a ton of lower end power (and peter off too soon) and you need to shift the curve up a little higher. Vettes are lighter and do not need all that lower end tq, you will have more that enough from the sheer size of the motor.
meaning the larger the motor the more tq it is going to make. The texas giant is a good cam to check out.

Thanks Jeremy for your input, I value your opinion alot, and I know you will be tuning my car.
On the Texas Giant Cam, thats from Texas speed and Performance correct? They also sell the Magic Stick?
I agree on the low end torque, and light weight of the vette, so I would be willing to give up a little down low, to see the nice top end.
In my case,what peak rpm should I be looking for hp peak at? 6500? or can it go to 6700? 6800?

I filled out thier online cam tequest, and put all the data in that we are using here.
I think they just have a scretary plug it into a computer, and email it to you.
I dont think their recommendation will be used in my case.

There is so much more to consider than the info that Cam Motion asks for. They can give you a starting point, but you will need to tweak from there. I'd suggest downloading a VE calculator and designing your own cam. This is what I'm doing for mine. Pick a starting point, such as a cam someone is using on their 415ci motor and change durations, lifts, lobes, LSA, and ICL to fit your needs. You don't need a big cam unless you want big peak numbers that you can brag about to all your friends, even though you have to spin up to 7000rpm to make good power and the car is difficult to drive in traffic. For reference, my 427ci will be getting a 226/242 112 cam, or thereabouts. Still haven't finalized it yet.
