Thanks
Thanks
I have no surging/bucking in mine so you will have no problem with a 224/224. its very streetable. Its all in the tune. so make sure you go to a reputable shop who are pros with LS1 edit. If you do a search on corvetteforum.com, youll find some vids of idle behavior with that cam on a 114.

I used to run a 224/220 116+0 and it was very smooth (nervous rapid chopchop), but good number capability and netted 11.3 H/C with 11.0:1 SCR
The 224/224 will act the same but be a little more exhaust biased.

Hmmm.... I don't know about that.
I run a Comp (TSP) 224/224 .581" 114+2 cam (ported heads, SW LT headers). Peak is ~6400rpm. A 116+0 will peak probably closer to 6700-6800 rpm.

I honestly don't think you are going to see a HP peak change going from a 114 to 116. The intake manifold is really going to try and keep that peak HP in the 6300ish range due to the runner length.
It will however move your TQ peak higher in the RPMP range.
I'm going to be trying a 223/228 XER 108/108 in my truck. Should have pretty good bottm end TQ but will be much lumpier and harder to tune. I'm suspecting it to still peak around the 6200-6300 range.

Got ya thinking Cam did I? My LPE GT2-3 came in today....Looking forward to getting it all together! (my lsa is 118.5 though with a 207/220 dur @ .050 and .571/.578 lift) Lingenfelter says it tops the LS6 throughout the whole band and has a baby smooth idle!

Ah, my FAST intake may have an effect on the peak power shift....although I never would guess (believe) that it would shift the peak by ~500rpm (if it were a 116+0 cam).

Yes you did. Let me know when you get it together. I would love to see/hear it run.

I'll be sure and do that....I'm still rounding up a couple of parts and will probably tear it down when the weather changes. I'll be sure and stop by when it's back together!

The 114+2 is about as rough as I would like it. The exhaust note is definitely noticable that there's a cam installed, but there's no hunting or surging at all - idles great, which is mostly due to the tuning after the cam install. Low speed is also fine, no bucking - unlike what I had a bit of with the LS6-cam when it was untuned.

Thay was with a LS6 intake.
A fast can carry the band a little further but not till 6700/6800. As mentionned earlier, intake design restriction.
Now keep in mind though that a 116+0 will rev high, I shifted at 6800, but it could go further.

Here's my curves, if this'll help:
224R (224/224 .581" .581" 114+2), Ported 243s, FAST90/NW90, SW LT Headers. (Baseline curves were LT Headers, LS6 Cam, stock heads, LS6 Intake)

Do you have a graph you could share. Your car would be a good exaple of what I am talking about. Peaked at 6300 due to the intake design but it carried the power curve well above 6300 right? Didn't fall off real quick..
It moved your torque up higher in the rpm band (came on later) and since hp is a figure based on torque and rpm it carried more hp past peak..
Although your cam is slightly different than mine 223/228 108/108, I feel they are similar enough to see the difference ICL/LSA creates. And it is a pretty dramtic change at 8*.. When I get the truck going I would really like to comprare.
