a cam with more lowend torque, help
a cam with more lowend torque, help I have had a 228/228, 588/588 114 cam for about 6 months now, since I rarely spin the motor past 3k I am barely seeing any of the gains. I miss my low end torque that I used to have but I don't want to go back to stock, any recommendations on a new cam.
I currently have 918 springs and 7.4 harden pushrods.

Well you can step down to a smaller 220ish cam, or if your budget permits a nice set of small port/high velocity heads, while raising your DCR would give you a lot of your low end back.

Well the afr 205's, Dart 205's while boosting your DCR would be a nice package, you would gain power all over the band. If you really wanted to step down in a cam you would have to make a good jump down to really feel a difference, like a 220/224 on a 110 or somthing equalivent to that. LPE sells some nice small cams, also you could try giving Vinci a call since he has a lot of cams that are specificaly grinded to for low end tq.
In honestly i think saving up for a nice set of afr heads and milling them to raise compression would be a real nice upgrade.

The TSP ported ls6 heads are a real nice head for the price, but they run a pretty large runner size which wont give you as much of a low end gain as say a smaller port head like the afr's or darts.
The Darts arn't much more then the ported LS6 heads and are a clean slate over the stockers which will give you more room to do somthing in the future, but it all depends on what you are really wanting to do.

Have you done a search? There are several good threads on low end torque cams. Basically, you need to shorten your intake side or in other words change your IVC timing. 216, 218, 220, etc. are common durations to build more torque down low.
Check with our sponsors, Vinci, Synergy, etc. all have good recommendations, look at Thunder's site for the cams in the "off idle" to 1800 range.

I have that EXACT same cam and TSP PRC Ls6 heads...My car makes 320rwtq at 2500rpms! 
Before I tuned the car it was extremely lean on the low end A/F was in the 17's and it caused me to lose approx 100rwtq until 3500 rpms. The car made a little less torque cam only but not much. My cam is advanced 4 degrees and still peaks at 400rwtq at 4650 and 435rwhp at 6300 rpms through the Ls6 intake and exhaust. You arent going to gain much if anything from a cam change below 3000. Make sure your tune is spot on below 3000 rpms. I have my A/F going to 12.5 on stab of the throttle. And yes I GAINED torque throughout the rpm band with the addition of a 237cc head... 
stock compression, stock valves.

It's not a dig, but I do find it strange as just about every time I get in my car I'll do a few WOT pulls to the red line - but hay I thought that was the whole idea of owning a performance car???
I am running one of the Vinci cams, the 056 with 216/224.551/0.551 115LSA and just recently installed a set of Dart 205 heads. The low end is excellent, and that was my intent. I don't race the car and was looking for a little more grunt in the RPM range where you don't get into much trouble 
I recently posted my latest dyno, 393 rwhp and 385 rwtq with the power peak at 5,800 RPM.
