LG Motorsports g6x3 l92 cam is in.
I removed my 248/254 cam from my 402ci,l92,l76 set up. I installed LG Motorsports g6x3 cam.It fired right up and caught an idle as if it were already tuned,never tried to stall. It has a nice muscle car sound and when the cutouts open,it sounds meaner.I took it out for a test drive and it seems to have some more power down low. It roasted the nittos in 1st and 2nd gear from 2,800rpm's to redline. It dont have the load up on take off that my other big cam has,I didn't have to get the rpm's up to go,verry smooth. It dont have any bucking at 1,600rpm's on the highway in 6th gear. Over all for this cam not being tuned it is flawless and drives great with no problems and It seems to have the power of the big cam. as for size all Louis stated is mid 230/mid 240 duration on a 111lob. my 402 dynoed at 517hp 468tq and I did not seem to loose any power,but gain in the lower midrange. I would say this is a great cam for the l92 set up if you want power and great drivability. I have ran ALL LG's x-cams in my ls1 with great results. I may dyno this cam and I'll make a track pass hopefully soon. I would like to thank LG Motorsports (Louis)for giving me the chance to try another cam for the L92 Set up,thanks guys.

From my past in cam swaps (i have done six)the tune will not be far off at all. tuning the cam will only result in like a 5hp gain from what the first dyno pull will be. It will take about two weeks but i'll post what I come up with. from driving my car this smaller cam pulls like the bigger one did,but drives much better.

Again guys remember,I will first track test and if I improve even only one tent then I will dyno tune it. if I slow down I will remove it for my old.
1ORANGEWS6-This cam does have a lot of *****,the low mid range is much better then my big cam. It sounds and drives great. I think you will love it if you try it.

Well,I did one test today. I have a bud with a built camaro ss. With my old cam at from a 60mph roll(we both have m6 w/4.11's)to 125 I could only pull him by alittle over 1/2 car till we hit our rev limiters. We have done this race several times always with the same results.Today we did the same race from 60mph to 125ish and I now pull him by 1 1/4 cars to our rev limiters. that is near 3/4 of a gain.I pull him much harder and faster now with the new cam. So,now I'm going to dyno and clean up the tune for this new cam,then to the track I go. Again,this cam drives much nicer around town with more lowend *****. Smaller is better....Maybe I should tell that to my girl

That sounds close to what I am going to run in my build. I`m looking at a mid to high 230`s and mid 240`s around 600 to 620 lift spun tight on some gas. Keep me updated on how that cam turns out for ya.

are u saying small cams work well with the l92 heads-
if so what cubes are u guys matching the l92 heads-before needing a decent stick in it-
Thanks

Both of them are running 402's but even 427's aren't running large cams with L92 heads.

I have a stock LS2 bottom end with unported L92 heads. Cam specs are 232/236 600/600 113lsa. Through a stalled A4 I made 450rwhp.
Congrats to the op. Sounds like you made a great choice.
EDIT-Now if we could just an aftermarket intake LOL.

I have had 3 l92 cars so far all 408's and I have an engine dyno I can use anytime and have been testing for my self but normally keep the lS motors mellow because they are for others that daily drive. I have my own L92 project now in a 408 being a larger cam version 244/252 .600/.600 on a 111ls and 108lc made good power on dyno 612hp. In the car this sucks it has a horrible off idle hesitation no power down low and feels like it would need a 5500 coverter to make a good drag pass. I think the air speed on the l92 ports is just too slow to create any kind on pressure on the intake valve between cycles and cam reversion adds to the problem or at least magnifies it. I am a firm believer in the 230 cam theory all cams in that range i have used or tried make very good numbers up top all the way to 7000 but have a great lower torque curve. The shorter duration creates more time for air pressure to build in the ports between cycles that is why it works the same for wider lobe seperations that eliminates reversion that can hurt the foward motion in the ports. I have had several people try to tune the car and all were good but it always had some hicups I believe were the cam and the fact its an auto on top of that. I have just switched it to a carb setup and it acts about 80% better more responsive only because i think there is less volume in the intake tract with the carb ? I am switching to a smaller cam and back to injection to finish my other tests ?

My goal is to dyno and tune this cam with in 2-weeks at most. I will try to post both graphs from one cam to the next. Maybe the tuner can print me a overlay graph. be back in a few weeks.
1ORANGEWS6-it sounds like every other choppy muscle cam out.It's on a 111lob and idles real smooth.
