Buddy,
Meet me half way, I think you chose the title of this thread performance cam shafts when you 1st posted it, so to me it belongs in a performance section.
There are many things done in past as "must do's" according to others, that I now disagree with, having done some things myself that did not net results expected and I've also learned from others, so please don't take it personal when I choose to think it's not a good fit for the basic 6.5 based on my understanding of the way things work; this is a discussion forum lets discuss it.
I'm more than willing to watch folks prove conventional wisdom wrong in cam shafts, ATT could not work either according to conventional wisdom, it was never heralded as a performance turbo but merely one to replace the GM turbo with, turned out that in some ways it does outperform the GM turbo.
As for your thought that I am pidgeon holing this, consider this until I posted in this particular thread today and we created the performance section, the thread was automatically pidgeon holing itself last post was 9-25-09 in the main 6.5 area. If I really wanted to pidgeon hole it simple as a lock thread so it would die on it's own burried deep into archived non active posts, or I could just have used a delete post function.
Missy Good Wrench, & a few others are on same page as I about cams as a power gainer for the basic engine, Yet you seem to think I'm the only one that has said I am doubtful it will net enough to be a worthwhile endeavour. I don't think its goin to work as SSD claims it will without doing some other things to take advantage of what might work in a tweaked cam.
As far as me saying earlier folks need to be less serious that was a collective statement somebody got upset when I said the Holset wasn't the best fit for the 6.5, I still stand by that, as extra stuff need to happen for that to be a good fit, and CIL6 suggesting I might want to disregard the assertions of a speed shop, I was not complaining about anybody jumping my case, I'm not sure of you singling me out on this cam thing though. If I'm misreading you I apologize, but that is what it looks like from this side of the monitor.
We are talking forced induction here on a relatively low rpm engine which should cover gains in the basic engine that hasn't been flow modifed in the intake runners or porting, or head flow changes, CIL6 is doing the things that would net gains accompanied with a cam change I would expect to be needed to get a gain from a reground cam.
Can we say at this juncture that we can agree to disagree that a cam on a stock 6.5 or even bumped up with a turbo, a reflash, a open exhaust, phaser gears, splayed mains, lowered CR will do much, I know guys running that way, have build an engine that way myself, nobody with that configuration has seen the need thus far to say I need a different cam.
So I'm going to stand by my recommendation that unless taking it to level that CIL6 is taking it to, once you do the standard bolt on mods you've hit the limit for where the bang for buck mods can take you. You can stand by your convictions that there is a benefit to a modded cam in the basic 6.5 and lets make a truce there.
Is this THE limit for the 6.5 most assuredly not, 6265 Racer is about as far as one could possibly go for now, I don't recall a special cam there.
Is the missing link that a cam would that get even more for the LSR, possibly CIL6 will let us know,
I'm dying to find out because it it works and can be easily plopped into a slightly beefed up 6.5 I'll be on the waiting list for one myself.
Before we spend a lot of time on cams however,
IMO fuel is the next shortcoming & we need to be looking at more fuel before cams, I could be wrong on that position and if proven otherwise I'll man up to being wrong, not the 1st time but would be the 2nd time
Possibly it would have been better to name this section as 6.5 performance/6.5 R&D
