Launching!
How is the idle? I would think fairly choppy with -2 overlap.

they had some interesting IVO/IVC and EVO/EVC as well. They asked me not to disclose all of that until they put them out for production. Interesting lineup though. The two small cams were great for stock converter stuff. Im excited to use them in the future for my dod delete customers.

I honestly really liked that cam. It was my favorite of the bunch.
Thanks for that, makes me pleased I stuck with my low duration tight LSA cam after a lot of mind numbing deliberation over it. I only have to think about how the car is used most of the time and It becomes easy to decide.
People say don't chase a number but that is not quite correct, still chasing a number but lower in the rpm were it's used most.
I have a graph out of street magazine article where a lot of cams were tested side by side and a 212/212 makes 50 ft lbs more than a 228/228 at 2200 rpm tested in same LS1.

I tune quite a bit of these and they will put down 210-220 completely stock and on a couple different dynos depending on what area I go to. They are 285 flywheel horsepower. So even with a 25% drivetrain loss they are 215
I started the runs at 2,500 with the smaller 2 and 3,000 on the larger since they shifter tq higher in the band with the stock converter. so its pretty much showing right where it comes in on each of them. Ill have to check if I have any other pictures. I dont think I do. I figured that would suffice since we had a baseline and so on.
These cams are all .550-.552 lift I believe. They are show by valve lift on their cam card. not gross lift.
Richard holdner did the btr cam tests and made 480 flywheel horsepower out of the 5.3 with stage 3 btr cam. factor that same 25% drivetrain loss. Thats 360 rwhp. These are a very comparable camshaft.
Ive had comp xer stuff on my old dynocom 10 years ago and they made 325-330's with 212/218 stuff.

Yeah I thought they dynoed in the low 200's and you confirmed that, but you showed a dyno that yours did 248 stock cam? When you say low 200's is that bone stock exhaust and tune and all? And yours is tuned with exhaust making 248? I'm in no way saying your numbers are false, I just have looked up dynos on these trucks for a while and numbers have been all over the map.
There's a couple of guys that have posted 240-250 cammed and tuned.. nothing seemed to make sense, so when you posted 248 stock cam I was wondering if yours was reading high, or normal or..?

One of the main ones I looked at in the past, when I started looking at drop in cams for my 2004 truck, was Thunderstruck's post. He was really detailed so I leaned towards trusting these numbers. But they also seemed low. But then again, years back I had no idea what one of those trucks would baseline
https://www.performancetrucks.net/fo...-531293/page2/
After that I did a bunch of looking on youtube and saw numbers from 200-300 on gen 3-4 5.3 trucks and I didn't understand how one guy would have a 5.3 truck with bolt ons doing 300 and another one stock doing 200 and another with a good write up and full details doing 250 with a cam.
For whatever reason when I did search for dyno numbers on 5.3 trucks (gen3-4), it seemed like I never got consistent numbers, and got dyno numbers with minor info on the mods. I kept seeing them dyno low 200's to as high as 330 with claims of being stock, or bolt ons only. There's a gen 4 5.3 truck on youtube supposedly doing 330 with exhaust and a tune. I didn't understand the massive swing in numbers and I still don't. Really doesn't matter just gonna trust your numbers here.
Add on top of that been talking a bit with a guy here recently making 250 with a cam, with bumped compression and a little headwork (it is a 4.8 but close enough).
https://ls1tech.com/forums/generatio...valuation.html
So again, it just seemed like I saw numbers ranging all over the map, thunderstruck and the other dude only made 250 with a cam and had detailed posts and likely built properly so I leaned more toward trusting those numbers since there was so much info in those posts.
Then I see yours with good info making 250 exhaust only and the loop of wtf just started all over again lol.
I apologize for clogging up your thread. I'm just going to take the info you provided as the right info and run with this..... 210-220 ish stock. 250 bolt ons, maybe 270 full bolt ons and tune for gen 3-4 5.3 trucks. And I'm assuming with full bolt ons a good tune 93 octane and light wheels they can do as high as 300
And then of course your cammed numbers. Thank you for the testing and info, I've been wondering for a while what these things do when solid information is provided.

I do what you do, I look at lots of dyno results and get an average, but !!!
Isn't it reasonable to assume dynos can vary plus or minus 5 to 10% between them.
Not only that it often doesn't reflect how fast the vehicle will be or how fun it is to drive.
Although the graphs are useful here because it shows the difference in the same set up on same dyno with the different cams.
