To the cam gurus. I know that there will be a need to measure valve clearance, but over all I want to know if a specked cam Dur @.050 238/252 625/625 115 lsa if that would work in an LQ9 .030 over.
I was actually thinking of throwing ported LS3 heads with a FAST 92 on top. I have everything to do it.238/252 is quite a big exhaust split, which from what I've read is normally used on an LS3 style head (as the intake flows way better than the exhaust), so might be a better combination is avaialble for an LQ9 (depending on the heads). As an example, say a 240/244 whilst still on a 115 would have less overlap, so possibly easier to tune and more driveable (although that's a relative term when you're talking ~17* of overlap at 0.050"), but more intake duration so possibly more power / rpm potential...
In terms of PTV, from what I've read it's right around the 231+ intake duration where you really start to need to check PTV, so yeah, at 238 you'll be well in to not only having to check it, but quite likely having to do something about it...
Although depends on gasket and heads, as above, just assumed stock.
No this is the combination that I'm going to do. I know that ultimately I have to measure everything. I also have in mind the GT11 cam. But definitely doing nitrous. I want to make sure I don't buy a cam before I'm sure that it will clear. Why I'm asking questions 🤘🏽👊🏽Cart before the horse?
Based on the little bit of info you provided, that stick is about 10° too big everywhere.
Then again, WTF do I know?
I guess me saying that I have some thinking to do and maybe going with a different cam wasn't good enough.What NotHubert is trying to imply is that you probably can't get any better cam advice than from EDC - cams are his bread & butter..
It's like you coming here and posting for handheld shield advice, and then ignoring the input of Captain America. Talk to EDC.
I'm not dismissing you I replied that maybe I should go with a different cam like a GT11 and got no response other then a snarky remark. How about this:No one listens to me....
I don't have a You Tube channel or an Instagram account so what I do isn't credible.
Thank you I'm open to other cams better suited. All I want is a streetlight to street light fighter. That was my fault in not specifying what I want out of a cam. I've had a high reving LS engine shifting at 6800 with a 7200 rpm red line. I'm looking for a cam that works between 1800-6500 rpms. Want to embarrass a few 392s. That's all....🤘🏽I definitely misread your post then. It sounded as if you meant, "nah, i'm doing this, i just want to know if it clears." Re-reading it, i get what you meant now.
However, there are probably a lot of cams better suited than your two current choices.
As far as the sarcasm, it's not that serious, man. We've all been knocked around on these forums and learned a lot along the way.
