Huh? Where did I say where the setup peaked? I didn't that I recall.
But the point was it was just a thing of amazement. The bottom end was built, and the car kept pulling pretty well, so he said screw it, let's see where it pulls to, since it shouldn't have been pulling that far, in theory.
Do you live the LS1tech theory only, bro? It was just having some fun since it wasn't supposed to do that. That car was a beast. Ran really good. Just that stupid gay 114 LSA wanted to keep pulling.

I'll be glad to take this opportunity to learn from ya, Predator-Z. Help me understand how you know where a cam peaked without knowing about the intake, heads, and exhaust. I'm pretty new to these cars and only repeat what I see happen. I don't know as much as you, and I always thought that a cam's peak was determined by all these factors as well. Which explains why in my dyno graph in my sig my old 224 was just peaking at 6600 (when we let off because my PTV clearance was low when we set it up and couldn't raise the rev limiter as high as needed). My heads were, from the way the cam wanted to act big and for lack of a better term, "too much head" (with too little compression) for the little cam. At least that's the conclusion that me and the builder/tuner came to.
Thanks in advance for any help, and Merry Christmas!

The reason why Predator Z can make the statements he does is only because he's either owned, tested or seen literally hundreds of cam combinations with LS1s over the years. Once you've seen over a dozen G5X-3 cam dynos (either on 112LSA or 114LSA), you begin to form opinions about them from experience. You get to know at which rpm they peak and what kind of power they make. When running an LS6 or FAST intake, they will make peak power in the 6300-6500 rpm range.

Personally, I'd grind it straight up and put in an adjustable chain during the install. That way you have the freedom later to advance 2* if you want more power down low or retard 2* if you decide it peaked too early. 2* won't make a huge change but can fine tune your power curve enough if straight-up isn't good enough or your goals change a bit.

welp, to help you pick the cam for me here is what id like to have...
I want a LOUD, HARD LOPEY cam that will sound really agressive on crusie ins and such. My car is NOT a DD in fact it only gets drove on warm, sunny, summer weekends, so high lifts and long durations dont scare me...also its an automatic and i dont wanna STALL the crap out of my car (thats what makes my decition so hard or id just throw in the T-REX)...also i want it to be a street beast cause i dont go to the track much, yet i do some. this is will be a cam only application for a good while as well considering im a college student will small money funds...
thanx in advance and if u have any more questions, ask and ill answer

You want a big cammed small stalled street beast. LOL
You guys are waisting your time giving him advice, look at the cam he's proposing. Just another parking lot poser.

I always have that happen. I jump in to smart off about someone's spelling, and I misspell something while doing it. Ask Earl. It's karma.

There's enough slop in cam grinding, that they can be off a degree or so, the even grind may end up with an odd ICL. I suggest 2* increments because that's probably enough to register on an assdynometer. I haven't used it, but comp makes one that is infintely adjustable. I have the reliable 2* increments.

Oh and you can't have it all on a cam. Gotta choose. You can't have a track beast and a tame driver. It doesn't work that way. So YOU should decide what you like if you're gonna want a combination of performance factors.
