Cam advice? Split, reverse split or equal?
I wrote: I dont know how many times I've said, the whole combination thing, but yet you keep going back to what i said in the 216/220 thread. Jarrod and Chris both have said, it is a restriction. (80%) range. So, whats wrong with saying were intake restricted and a reverse split may work better?
you don't have to be mean. I just thought it was silly that I'm using that word in a camshaft thread.
Thats true, and I dont blaim you for it. But as a few have said, if you match it up to the flow characteristics, perhaps at given lift points spec'd you might see a reverse split pattern.
not to me. just difference of opinions on this matter. i'm not trying to be a jerk. sry if i come across like that.
so? have they not? 
it takes alot to sway someones opinion. and i am way to lazy to try and make you feel the way i do. others have layed down some facts. thats good enough for me.
Yes Mrr23. And I think thats why Mr. Straub made a good point by giving an example of this nature: his camshafts may start out as a traditional split at a given lift, but might be a reverse at another.
and how you are (oh geez -->) stereotyping
so far the only results i've seen any benefit of having a reverse split cam is if you want to turn past 5500 rpms? i can only draw the conclusions i have with the evidence presented in front of me.
yes between him and me it's a pissing contest.
and he hasn't it's taken others to try and help him justify it.

now you are saying the whole combination thing. but over in the 216/220 thread all you kept coming back with is the LS1 intake is restrictive. and i asked you to show me why it is. you didn't. hell i pointed you over here and even tried to help you out with proving your point. but, like you said, you are too lazy to prove your point. it's taken many posts and a couple people to help me get a better grasp of a reverse split cam and it's effects. i don't take people at their word. i want to see proof.
here's another little saying i go by. believe none of what you hear and only half of what you see.
one day we'll have to meet up and hang out. i like people that stand up to their beliefs. and will defend it until proven otherwise. as you can see, that's me.
i'm glad to see you aren't taking offense to all this. it's all in learning. but i was getting tired of the poking at me with the stereotyping thing and all.

the Z06 was a 415 cid 2 stage n2o. ran 9.60s. their 99 c5 test car on that page was a heads cam car. ran 11.44 @ 122 the current 03 c5 has run 12.07 @ 113 cam only. and on DRs. if they ever put ET streets on it, it'll go 11s. heads are next on the list though. but the 03 c5 is their street racer version.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo Got my latest issue of Chevy High Performance. They did a Patriot Performance head/cam setup. They offered the head flow numbers, so I thought I could relate it to this thread.
-----In.---Ex.--- %
.100 82 65 79.2%
.200 150 124 82.6%
.300 212 160 75.5%
.400 254 196 77.2%
.500 290 220 75.8%
.550 301 226 75.1%
.600 314 229 72.9%
Now, using J-RODS intake restriction chart. I tacked on and got the following:
.200--84.5%
.300--79.2%
.400--83.3%
.500--85.4%
.550--85.3%
.600--82.2%
It would be nice if we could see what a set of Long Tube headers would do.
Pretty interesting none the less...

btw, those flow percentages were calculated using the LS6 intake restriction figures.

Mrr23,
Just realized you did sorta the same thing with the 5.3 flow numbers I posted a while back:
Those percentages you posted, (and the ones I figured) dont show the whole scenario, seen as the exhaust was not inplace.
With the numbers you supplied and not figuring in the rest of the setup. Yes, a traditional split might be used inbetween .200-.300 lift
In the one I supplied, a reverse split might be used @ every given lift.
Fair to say people?

Seems that most, start at an intake bias-even out-and then return to the intake restriction.
Any pattern? or in a detailed explanation, what causes this?
