And what did we learn? You bump up the cam you need to bump up the converter.

You don't have to have the lopey idle and irritating manners of a small lsa, large lift/long duration cam.

Check out some of Ligenfelter's cams. Very smooth idle and great street manners while making big power.

Considering that a cam swap on a l99 isnt cheap might as well go with something thats gonna give you more power. I sure GPI or Lethal can work something up for your needs.

Yeah, with parts and labor Im looking at about $5500.

I was on the same boat with my cam but I have a ls3. At first I wanted something tame and was worried about drivability. But I figured I might as well get the most out of it while im doing it. I ended up with the nightfury and it drives awesome and makes great power im glad with the turn out.

I feel you on the drivability part. Some people can live with surging and bucking and to me it just makes it a pain to drive the car. You can get a nice cam that you can drive and not have to "just deal with"

One recommendation is Ls9 cam, has a perfect smooth idle, you can even drop the Rpms down to 600 or so at idle to sip a little less gas, it's cheap (125$ for camshaft alone) and effective and will give you a very modest bump in power close to what you're hunting, while remaining perfect to drive. However there are plenty more options and ones that will get you more power without sacrifices.

I have a custom grind cam, I currently have it set to idle at 750 and it has a lil chop to it, but at 1,000 rpm it's smooth. You having an auto you could maybe eak out a bit more before you get the lope you don't want, but not sure how your auto would take it tho, not knowledgable about autos. LOW 220s intake and high 220s exhaust on a mid teen (15+) lsa should put you in the ballpark you want and you can set the lift to whatever your comfort is.

Personal experience of 3 cams in same motor(NOT a STOCK motor) on a 6-speed car:

236/246 110 lsa i made 485tq and 515hp couldn't drive below 2,000rpms without surging. I hated it. Couldn't use 6th gear ever even on highway the sob jerked around

The ls9 cam in same motor made 480tq and 485hp. Smooth like stock, perfect DD. But I knew I could go bigger...

Custom grind makes 525tq 505hp NO surging, daily drivable, and it's beast.

I did this myself for about $200 and then sold the stock cam, gear and bolt for $100. LS9 cam has a touch more lope than stock, but I also put on headers with no cats and it does pop some on deceleration. Given I see people are paying 5k to swap cams, could be the best value on any mod I have ever done.

There is a really good DIY on cam swaps in that section. I learned on SBCs and BB Mopars and this was the first time I opened up an LS engine, but I felt it was no big deal. Certainly a lot cleaner than the old junk yard motors we pulled back then.

I have a 2010 L99, MBRP catback, CAI by C.A.I and catted ARH tubes. I am considering a cam upgrade but do not want the obnoxious cam lope, as this is more of a daily driver and not one sees the drag strip as often as I would like.

Is there a cam out there that will give a 25 to 30 horse gain while maintaining the stock exhaust character? Smooth and baritone versus crackly/poppy?

ask me to help build a 412ci or a 418ci and I am good, more modern engines and I am a touch out of my league

Ooooo Wee! The boxes on these cams should have a similar disclaimer to erectile disfunction pills.... "if you have an erection lasting longer..."

OP, you can achieve what you want very easily...as many have said. Something in a 224-228 dur. and keeping lift under .600. LSA in the 115-117 area. Its not all about big cam/big numbers. All those big numbers do you no good if they don't kick in till 5,000 rpm. We have big heavy cars. Your smaller cam will give you max torque from 1500-5500+ rpms (where you need it). Also, keeping it small will avoid the extra expense of adding a stall converter. Good luck.

Avenging Orange is right. My NF cam is one of the larger street cams and on the dyno sheets its close to stock till you hit the upper rpms starting about 3500+ it starts making power and at 5000 thats the sweet spot where it really makes a difference, 55rwhp to be exact.
