Cam advice? Split, reverse split or equal?

my original concern was someone saying the LS1 intake is such a 'crippling restriction' that a reverse split was in need to compensate for it. the only two dynos in this thread show it's not a restriction until 5500 rpms. when you are trying to exceed it's designed parameters.

my only reason for being in here was about reverse split cams solving a 'crippling restricted' intake. out of the 2 dynos shown in this thread, neither reverse cam made any appreciable difference until 5500 rpms. even a single pattern out did both splits under 5500 rpms. the intake is not a restriction until you go outside of it's designed parameters.
lol. most pick the cam last. whoever custom specs a cam to there engine and then goes out and buys some headers is dumb. 
i'm sorry but that has to be the most retarded argument i've ever heard. seriously. oh geez.
oops you edited.
this right here was my reference definetly still laughing.

you sure can. you can also buy a shelf cam that'll do the same thing and not have to worry about having to buy another cam later just because you changed from stock manifolds to headers. after all a custom spec'd cam is designed for that exact application right?

also, its the average consumer that bitches and complains the most when there package they buy doesnt put out the same numbers that a person with the same or similar mods does because that person maximized there combo to the fullest.
wait and think about what you said.
a camshaft custom spec'd to an application. then a guy goes and buys headers. now his setup isn't custom spec'd.
but if i go buy an off the shelf cam specd to fit a bunch of motors, or a best guess between alot of motors. swapping headers afterwards wont be a big deal.
its like your saying the box cam is made to work with all sorts of motors so it wont matter.
idk. i just thought it was goofy.

i just spent $1100 on a set of bassani headers w/catted y-pipe that only gave me 10 rwhp. man that equates to $100/hp . but if i did a cam that would've been about $600 inlcuding springs. lets say it gave me only 20 rwhp. that's $30/hp. damn which would you do first? people look at cost as well as parts.

well it still looks like candidate for either a single pattern cam or standard split using everyones basis for 75-80% before a reverse split would be in order. but now we have some info on what a head can flow with both the intake and exhaust attached. still not seeing the over 80% when and exhaust pipe is attached that some were speculating would happen.

I run a mti stealth 2. Its sounds close to stock. Power is up everywhere. I think anyone who would want a vinci grind cam. A smaller area under the curve cam i mean would be smarter looking at a stealth 2. Its a reverse spilt. I run a ls1 intake. This is why i went with a reverse spilt cam.

i think you are using terms incorrectly there. clarify what you mean by smaller area under the curve.
and you based your decision of using a reverse split cam just because you have ls1 intake? when i do put the 047 cam in, i'll be keeping my ls1 intake as well.

Before I tell all of you my mods let me tell you about my brain fart. I forgot to turn off the A/C durin g the dyno run. I know, I know! Well anyways these are my mods:
1. Custom 93PONY cam 220/220
2. Asp pulley
3. 916's no titanium retainers(they sent me the wrong ones)
4. LS6 intake
5. cheap deck lid
6. Stock roller rockers (yella Teraas waited for install)
7. No tuning
8. Jet Hot headers and off road Y
9. Magnaflow catback
The car was running lean as high as 15.0 A/F in some points. 13.8 from 4200 to 6100. The cam should make power to 6300 but the rev limiter limited me. Anyways, I made 394.5 RWHP SAE and 377 lbs torque SAE. The cam made over 340 lbs tq from 3100 to 6000 RPMs. The guy said that with the A/C off I would have made over 400 HP. Sweet! Major brainfart but I am still stoked.
The Yella Terras go on this Friday and I am going to fix the restriction in the Y. It shrinks to 2.7 inches where the Y goes in the reduced part of the catback. I still have to do the throttle blade mod and install a better deck lid. Then there is the tuning. Finally, my ram air doesn't work unless I am moving over 40mph. THis thing should scream when I am all done. I figure I should be right at 420 RWHP and 390 RWTQ when I am done. Thanks shaun for the sweet cam.

I have seen the light. Im going to order a vinci .047 cam too. I made a big mistake useing a stealth 2 cam. The vinci .047 will make my car fly. The vinci .047's cams area under the curve is so much larger than my mti cam.Mrr23 your a good sales man.Thanks!

No, mine is 232/232. Seems to work well. I'm currently at 11.0x @ 121-3 with a motor that has 20% leakage. I don't know exactly how much the leakage hurts, but it must be some ...
Ed. that stinker. He's gettin more business than you'd think around here. 
Critter.
whos lobes? guessing comp? xe-r profile? did you do your own valve event choosing w/ the help of Ed/Shaun?
