from what i've been told by Mark over at comp when i ordered mine, the reason we dont see much bigger splits than what we do is because of the intake to exhaust flow ratio. we have great heads on our motors and we dont need a whole monster of a cam to take advantage of them. stock heads for example flow (roughly) in the 230's on the intake and 200's on the ex. that puts the intake at about 86% of the exhaust. you really dont need to split the cam any more than 86% I/E wise to keep more of a flow balance in the motor. now take a look at some of our ported heads that make it closer to 92% i/e flow ratio, and you start to see why more and more single patterns as well as reverse splits are being used to keep tq numbers up there. you dont need nearly as much exhaust flow as you do intake because of lesser volume of the spent gasses. make sense?

this is why our cam patterns are so signifigantly diffrent than the LT1, SBC and other conventional small blocks. this same ideology applies to other 15* and 18* cyllinder heads too. hope that makes sense. i think i got lost in there somewhere too. :D

See, I also agree with this point. So far, I haven't seen any bigger than a 6 degree split in either direction though.

G5X-2 232/240 8* split. It's doing quite well on the LS1.....

yeah? whooptie doo. you think it runs that way because it's on an 8* split? i really wouldnt have as big a beef with this g5x2 hype if it werent for the BS "give me money" marketing tactics behind it. that cam was designed to make the most out of a set of heads.

BTW, mine's a 6* split and it's doing alright too. but it's not because of that.

ok, now that aside, i really dont want to turn this thread into a LG bash-fest so im going to stop there. just remember a cam is only one part of the bigger picture. just because a "cam only" car runs a good number, remember, there's always a reason why. i love telling people all i have is a hotcam and headers after a race. does that make me the fastest "cam and headers" car in the nation? ;D just a thought.

yeah i do :D

i think it's the heat here in TX. hehe.. i gave fair warning there too, just needed that out of my system.. yeah, i have a serious problem with the marketing sceme there. outrageously overpriced gimmicks are one of my pet peeves.

I have a used 228/228 .588 cam here if you want to buy it at a good price Brian

I wanted to go with a 230/224 .575/.563 111LSA, but I was told that I would have P-to-V issues with stage 2 5.3L heads. I just don't understand, especially if I'm not having the heads milled. I was also told the cam would have to be revved super high to make power?

Had to settle on a 228/224 112LSA

But rather than making this about the G5X cam, how about another example: LS1 Grand-Am Cup, 239/251 which happens to have a 12* split and is capable of 470RWHP (as I stated previously) with a stock bottom end and LPE CNC LS6 heads....

Lets compare apples to apples here... the LS1 Grand Am Series calls for a cam with greater emphasis on the exhaust side b/c an oem exhaust manifold is required on the car.
