HOW TO MAXIMIZE 6.0L LS2 POWER. THE FORGOTTEN ALUMINUM LS! CAMS, BOOST, NITROUS, FULL DYNO RESULTS.

[@kennymilton7457]

These videos keep me up all night. With the constant back and forth of whether to build a motor or just mod the one I already have, these awesome videos don't make it easy for me. They all sound awesome.

Thank you Mr. Holdener, no one really goes into the LS2. Very much appreciate your time on this for us niche motor guys who don"t plan to go LSA or otherwise. Gonna use this as a reference for the upcoming mods l have planned for mine. 🙏🏾 Thank you again you legend!!!!

[@randyjohn1615]

Love these last two episodes more than most of these videos as I have a heads,cam 06 GTO that I'm going to install a VS 7875 on.I've been contemplating a head swap to broaden the tuning window. It's a huge incentive to get this project underway. I appreciate all the videos that you put out every week.

Awesome! I have an ls2 in a gto! Can’t wait for more

[@baby-sharkgto4902]

I use to have one in mine

[@jacobhoke581]

this is great i just got some ly6 internals i was planning on putting into an ls2 that i saved from being trashed due to a crack i welded up on some of the transmission mounts can’t wait to get it going 🎉

[@Carguylogan]

Good timing. I have a 2006 Corvette with the LS2. I did a FAST 102, TSP long tubes, 3000 stall and I'm currently doing a small cam. Cam Motion Titan 3 .600" lift 224/228 duration and 113+4. I'm hoping it will give a little chop and 40-50 extra hp while still being a mild cam that doesn't beat up the drivetrain too bad or kill my fuel economy. It made 385 wheel thru the auto before the cam.

[@swappedoutZ71]

How you like it? I have a 224/230 with 109lsa in a lq9/243 head and it's fun. Plenty tq but I upped it to 11.5:1 with the worked 243s

[@dover1966]

I made 433 whp with intake cam and headers only recently put a fast 102 tb and fast manifold Im probably at 460 whp with that once I put heads I’ll push 500 plus

[@Carguylogan]

@dover1966 If it was an LS2 that's just a happy dyno. I made 437 wheel on the tuner's dyno. Took it the following week to a dyno I trust and it made 403. A manual will make a little more of course. Probly 420 and with a bigger cam maybe 440. But trap speed will tell you for sure. 460 wheel is 126-127 mph trap. Let me know when you get that 120 mph slip and I'll show you a 400 whp car lol.

I got a 07 classic with a 4.8 soon as m broken hand heals up ill be installing a truck noris cam 'springs required' with a fresh set of 706 heads 1 7/8 long tubes with speed engineering full exhaust, BTR LS7 lifter trounion upgrade and the BTR stall. Not sure how good the sall is havent hurd mucb about them but hopefully it all works out good!!

A Richard I found out what was wrong with my 2006 Chevy Silverado l59 vortec 5.3,well a lifter not only broke off but just before that it was literally grinding a grove into the camshaft

[@proflow95gt]

Richard, as a previous ford guy that is working on a resto mod corvette your info has been a huge help to me in learning the difference in the Chevy power plants…. Do you have a recipe of parts for me to get a 408 stroker to 600 Fwhp NA? I was looking at using the lq4 block to build on as the extra weight isn’t a huge issue. Any help you can provide would be awesome!

I have a crate LS2 that I was thinking about putting in my 1500 with a small cam but tow with it & compression kinda worries me.

[@Groovy_ls1]

Do you have any videos on power gain an underdrive pulley makes on any Ls motors?

[@mirabalmedia]

Richard, If you had a choice between a BTR stage 2 truck cam or a Sloppy Best Cam on a 6.0 with 243 heads & 1 3/4 long tube headers. Which cam would you pick in your opinion?… I’m not really looking for top end power or racing. Probably more low to med range power. Just an all around good cam that will be reliable to drive anywhere with a good idle

[@cars_and_stuff]

I have a sloppy best cam in my LS2 and I love it!

[@mirabalmedia]

@@richardholdener1727 can the best cam run on a factory truck converter behind a 6.0 or will I need to get like a 2500-2800 stall or bigger?

[@tonymanns8249]

I'd love to see these cam comparisons with factory exhaust manifolds, factory cat converters, and factory mufflers, and accessories. I suspect that the torque and HP gains would be much less than this dyno is suggesting. I'd love to be wrong.

[@richardholdener1727]

YOU START LOWER AND END LOWER-SAME ROUGH PERCENTAGE

[@mikegillam1000]

How does the LS2 compare to the L77 from the Caprice PPV? From what I understand the L77 is an aluminum 6.0 but it’s only rated at 355 hp and comes equipped with DOD. Since everybody recommends doing DOD delete anyway would the cams you used on the LS2 perform similarly?

[@richardholdener1727]

NOT SURE ON COMPRESSION-BUT OTHERWISE CAMS WILL HELP A LOT

[@totensiebush]

Have you done any investigation on cylinder to cylinder AFRs (or EGTs) running a wet kit through an LS intake? I don't know how consistent I'd expect fuel delivery to be through that manifold.

[@richardholdener1727]

nitrous distribution video is up

[@jefflee8924]

Richard, what are your thoughts on why the ls2 made so much larger gains down low with the Comp cam as compared to the tests with the BTR cams in the ly6 6.0?

[@ZONES89RS]

The profile of the cam let the engine breathe and do it’s job. Stock cams are for emissions and mileage

[@jefflee8924]

@@ZONES89RS I understand that over the stock cam. What I'm asking is why did this cam make a nearly 25lb.-ft of torque & 15hp gain throughout the curve and all the way down to 3000rpm in the LS2 6.0 when in another of Richard's videos a Brian Tooley stage 2 truck cam has very similar specs but only makes maybe 10lb.-ft & 5hp more than the much smaller stock LQ9 cam from 3000rpm to nearly 4500rpm in the LY6 6.0? Is it a product of the almost 11:1 compression in the LS2 vs 9.6:1 in the LY6? Is it the cathedral ports vs. rec port heads? Or does the Comp 265 cam have much more aggressive lobe ramps than the BTR cams?

[@ZONES89RS]

@@jefflee8924 ah, yea the LS2 cam itself is not a tow oriented grind down low. So that is more than likely what you are seeing. The truck cans are made for low end grunt for moving heavier rides and towing

[@mikebaylis5350]

I understand you had stock injectors which I believe are around 33lbs ? We have a similar set up, and need to retune, but I was wondering if The stock injectors are acceptable? We are running NA. W/103mm TB and intake.

[@richardholdener1727]

33s will support over 500 hp na on gas

[@willfleischauer]

How big of a cam should I put in my ls2 with stock intake and stock heads? I’m new to building engines and I hear mixed answers It’s not my daily driver so I’m ok with a little aggressiveness

Is the LS2 able to be pushed into the 4 digit range and if so, what would you need to have done to the engine for it to hold it?

Take an lq9, swap out the 317 heads for a set of 243/799's, and you have an iron block ls2. People have been taking lq9's out of Escalades and doing this for years.
