My goal is about 450rwhp if I go with the G5X1 would that be possible?

-I want gears but not sure which is best I've heard alot about 4.10s

This link has a post of 450rwhp with similar mods that I want to do...

But what is the difference between 114 LSA and 112 LSA what does the number mean?

Simply stated; LSA is defined as the lobe separation Angle. Without getting to technical, think of a 360 degree circle in terms of the peak of each lobe intake and exhaust. The distance between those peaks is meausred in degrees. 108,110,112,114 etc. Most ls type motors driven on the street function well with LSA's between 112 & 114. For example, a cam with a 112 lSA gives up a little low end but the midrange is great. A 114 LSA has a wider torque band which is more consistant throughout the RPM range to the redline. I've used both type cams in my LS motors. In my LS2 I used a 114 giving me a good low end and power. The duration was 224/228. A great street cam with my 215 ET heads, FAST and the rest of the standard bolt ons. When I moved up to a 427
L92 motor, I went for a 112 LSA , a somewhat small cam only a 232/234 duration. This combination made for a great daily driver. Because of the 4.100 stroke Loosing some low end with a 112 LSA was more than made up with the longer stroke. This also gave an awesome
midrange which is where this car spends much of it's time. So selecting the cam's LSA is best determined by what type of driving your going to do, and what combination of parts your going to use.

So...
Narrower(112) --> better mid and top
Wider(114)------> better low end
When you say low, mid or top what rpms are we talking.
My first impression is to say I'd like the 114 for the better low end like at the track or for just daily driving to get more torque (thats if I interpreted your reply correctly)
But if I go for the 112 how much low would I actually be losing or would I just not be getting as much as the 114 because once you get going you would want that power on the top end right?
ME
<---thought that would sum it up.

Thinking about it now and looking at other threads I think a x1 or x2 would be better for me. Also my goal is only about 450rwhp and I think with all the mods here I should be good. Right?

-Dyno-Tuning
I'm still confused about the 112 or 114 though. Like which would be better at the strip, track, DD? I know one loses low end but does it just not get as much as the other or does it actually lose low end?

I think the G5x3's duration is in the 240's int and ex. With that a 6 liter LS2 is most likely going to idle like a paint shaker. You should have great power at the top end, but ask yourself how often you drive up there? A daily driver; define it. I'm not saying you woun't like it, but you'll make compromises to have it that way. We all do. You can't have it both ways. You need to be honest with yourself about what the car is going to be used for and then decide how you want to mod it. Most tunners really don't care what you want, they need there work to make a bunch of power because that's what sell parts when they post on this forum ie (Dyno sheets). It just good business. There not doing anything wrong, there just good businessmen. I suggest that you build the car the way you want it not the way they want it. MY opinion.
The car has a significant lope and does shake at idle but I would not call it drastic. I don't think you'll get 450 RWHP with the G5X3. Maybe with an agressive tune.. but then I think you would have even more lope at idle.

I don't think you will see 450 RWHP with the X1 or X2. If you get up to the Bradenton area, I'll take you for a ride and you can judge for yourself if it is too agressive for your driving habits.

Thanks for the invitation. I have family in St. Pete so I'll save this thread and if I go by there before I decide on which one I want I'll shoot you a PM and I'll stop by.
what do you think would be realistic rwhp with those mods? Judging from the hp numbers I want I'd like to get the x3 but I'm not about to sacrifice an extreme idle for more power.

I'm not clear on the HP for your headers, but I would guess you would be in the 440's with the x3 and the FAST. Give Anthony at LG a call and he could tell you what HP numbers would be for the other cams.
Is this going to be a daily driver or a weekend car?

It would be a DD. The cam wouldn't make the car any louder while cruising would it? Just change the idle which would prob. be ok with me cause I don't idle often and it would sound cool when it does but I don't want it to drive bad. I've read Joe_G's threads on his x3 install and he says it is his DD also and he has no problems with it but I still think I need to hear it before I can do it.

I like the setup in my car but it is closer to a race car than a DD. I would not want the G5X3 in my daily driver but I'm 40 something going on 50 something
I would highly recommend listening to and/or riding in one before you purchase one.

If those headers have drone in the 1500 to 1900 rpm range, the 4.10's will put you in a better rpm range in the cruising ones. The 4.10s are a kick however in the 60-130 track competition I could not get to 130 in 4th per the VBOX we were using-I kept bumping off the rev limiter at 128.5 even at 6800 rpm. see sig for tires, etc. I had to shift to 5th
You probably know that the dyno will be less because of the 4.10s. So say you wanted 450 and got it with 3.42 stock rear you would get say @ 435 with the 4.10's.
Don't underestimate the FAST ported. I got 430 rwhp with similar mods to yours without the FAST, another 20 is doable as per their advertisement on the box itself.

But you are correct, you should check it out first. You are welcome to come over to the corvette challenge at moroso on 2/16 and check out my and some other cams.

Thanks for the help guys. I was in wally mart today and happen to find a Super Chevy mag that was talking about cam shafts. How perfect is that. So i've got that and understand about the lobe and 112 and 114. But the final decider for me will be the sound. I'll mark the calendar 2/16 at moroso and maybe I'll be able to get out there.
