2009 LS3 MN6 Base. Just like the title says - what's the biggest cam you guys are running and have no daily driver surge? Thanks.

The secret to a good dd cam on an stick car is a small cam with a great set of heads while you still get the sound you want true a nice set of headers and exhaust set up it just turns the car into a lot of fun.

I've got 1 7/8 Kooks, coated, ported FAST 102, NW TB, stock 2 1/2 M2W exhaust. Seriously looking at Trickflow 255's. Tax return's burnin a hole in my pocket. Got a recommendation on a cam?

I'm a 08 LS3 MN6 base. I'm running KOOKS 1 7/8 LT's, HF cats, x pipe, Corsa extreme, UD pulley, Halltech Superbee, trunion upgrade, and Texas Speed cam kit(229/236 with 112 LSA)! The car isn't my DD, but I drive it regularly throughout the week and it shows to be very DD friendly with virtually no surge!

I'd want a little negative overlap for sure if wanting no surge. Something like a 224/230 115+3 should make you 450-460 rwhp with near perfect manners. That's assuming full bolt ons would go with it. Pat G can spec you a cam for just a few bucks. He can get you exactly what you want. Don't settle for a "shelf" cam that may or may not be what you're looking for.

I do will get back with part number and specs.

To make power a few good parts can go a long way and the list you are showing is top notch.

Trick Flow 255s are incredible.

The 2 1/2 will work well is you take it at 3 inch past the center of the tunnel plate and use a smooth gradual turn down to 2 1/2 before the axle back connection.

I can't see ported or aftermarket heads being money well spent on a mild build. Sure, you'd pick up a few ponies....key word being "few". Stock LS3 heads flow pretty damn good as is. Before fooling with heads, I'd seriously look at forced induction. You can add a blower, leave everything else stock, and be over 500 wheel horse power. And it will daily drive just as well as it does now. To get that much power with cam and heads, you'd spend almost as much, you'd lose your perfect manners and fuel eco will be less. Way less in city driving.

I had my LS3 heads ported in conjunction with swapping to headers and I already had a small cam. My car also had LS7 manifolds so my header gains were a lot less. You can look here to see the dyno results of those changes.

That said I don't think the heads are real cost effective, definitely not before a cam.

The Hinson mounts helped with my lumpy cam. Many people have worn out motor mounts and don't know it. If you see a rusty looking stain under the mounts, chances are they need to be replaced.

Before the build we (my son the tuner here and me) base line the car with all the freebies (safe for the cold air intake) ported throttle body and intake and because the intake was off I match ported the intake ports on the heads.

How few or generous depend on what you do how and who, see below an example of heads, cam and headers only effect on an stock ls3 block using Trick Flow 255 heads.

SAE 560 - 403= +157 whp

SAE 575 - 397= +178 wtq

Standard numbers minus base line numbers same engine.

Mine is PatG speced cam ground by and bought through CAM MOTION, 220/242 .626/.598 119LSA +4. Some say its a mild cam with maggie Hearbeat but runs well. LS3 2008 base. Thanks to Rodney aka old motorhead.702 hp 602whp 540rwt.

Thanks I've done a lot of research and read a lot of reviews. next years tax return is gonna be exhaust i think. full 3" akrapovic.

deadsexyii

thanks but FI not my style. I am basically after the nastiest NA build I can while retaining stock like drivability. I'm a city boy and a lot of my time is spent at 1100RPMS going 35, unfortunately. I don't want to have to turn 1600 for a smooth ride.

Our Stage III Cam is excellent. It makes big power and has superb street manners. If you decided to do heads, i'd CNC your heads. LS3 heads are great. Also, while heads will make power, they don't provide much bang for the buck. Feel free to call and chat with me sometime and we can help get your dialed in within your budget.

All the best,

Just changing out the cans won't get you much if you already have NPPs. Even the base mufflers aren't power robbers at your proposed power level. Unless you're infatuated with the noise those things make, I'd spend the money elsewhere.

scottg

old motorhead is right. .I did put 3" pipes on, 1 7/8 headers, but kept over axles and mufflers with npps just to get the exhaust out faster and sounds very good IMHO.

xBoostx

That will eliminate the exhaust limitation and will sound great specially after cam install I have full 3 inch with Corsa sport and those sound fantastic no drone.

It's really all in the tune. I daily drive a night fury cam, and it drove like crap til I took it to Pat G for a tune. Now it's great.

Honestly your best bet would be the stage 2 from tsp or btr and get a good tune on the dyno and the street
