Not sure who is funding your research but the numbers as you openly portray them, don't lie. Honesty is hard to come by on the interwebs...yours is def appreciated.
I have tuned several of these in multiple trucks in various builds. The Chopacabra seems to have more noticeable low end tq prior to the 2500rpm mark. Truck Norris “takes off” right at 3600rpm in a 5.3 and 3400 in a 6.0L. That is where it seems to come alive in the trucks where you are limited to timing on the low rpm due to weight/load. You will 100% want a stall and a solid rear gear 4.10-4.56 depending on tire height and weight to optimize these cams. I tow with my truck99’ ex cab 5.7L and it needs a 4.56 and a 3k stall to mitigate the low end tq loss in dynamics below 2k rpm and opted to use a custom grind 213/220 .575 113lsa+4 cam. Hasn’t hardly any lope but has more low end tq 2-2600rpm than the truck Norris hands down. Very noticeable difference especially when towing
Hi Rich, love the sheer amount of testing you do, but can i ask a small favour, particularly with things like cam tests. I noticed the dyno console shows manifold pressure, any chance when your doing comparos you could let the engine sit at a nominal rpm, say 1000, and show what vacuum its pulling. If you have two cams that make similar mid and peak but one has oddly more vacuum, then for a stret car, take the one with better vacuum. Cheers.
Ha ha I just noticed something. The big truck torkinator is Summit’s old stage 1 turbo cam renamed. Look at the images at Summit for the cam. Same specs, same part number (8728R1). Different name. Marketers. Every cam is a turbo cam.
Thank you Richard for the plug explanation! I love your dedication!! The saying was if you drop a plug? Throw it in your neighbors yard and get new a new one!! I wish we had this info back in the 80s!! We were guessing with all the new electronics and fuel injection just coming out. Could not tune the factory ECM so we were carbing the vortex heads and made good power but not like the LS platform!!!
Proves that similar cams produce similar results in terms of power and torque. For many of us, it comes down to price, quality (or perceived quality), availability, and customer service - not necessarily in that order. I tend to buy again and again for companies I trust that demonstrate great customer service. In fact, I might pay slightly more for their products as opposed to cheap stuff of questionable quality with little to zero product support.
My build is a '93 C3500 CCLB with a 153k mile LQ4 and a Truck Norris cam. If it was a regular cab short bed, it would get a turbo. But kind of pointless for my 21 foot long truck, lol!
Lsa plays a role in useable powerband. No cam is perfect at all rpms to build the highest hp and tork at that rpm. Only an adjustable cam could ever give us the max power of tork and hp at every rpm. But since a cam cannot be adjusted in the way the engine needs we have to pick one that gets us an acceptable power curve. What tork losses down low are acceptable for power gains up top. It depends on your application and intended goals. Are you aiming to build a low end towing motor with a little mid range or a mid to upper rpm power combo. When unsure go with an intermediate cam. The best cam is not always found at the bottom of the list in a cam catalog. A custom cam isn't usually needed as most cam companies have a good diversity of cam choices. And it costs more time and money to get a custom cam made. Most people couldn't even fill out a custom cam order form. Bloodviking
For us with tight spaces, it would be interesting to see some tests with stock manifolds vs holley LS cast manifolds vs short tubes vs long tubes on one of these cams.
@@richardholdener1727 understand that long tubes bring great results, but it would be nice to know how much is being left on the table sticking with stock manifolds and what benefits if any comes with something like the holley LS cast manifolds
@@captthrottle I know he’s done a test on that very thing but I’m sure it wasn’t with these cans. What he’s probably say is that compare the LTs of this one and the one he did the test on and split the difference between the cams. That at least to me is what it would be and he’s safe about all the cams on all the different size engines he’s tested.
@@captthrottleyou won't gain squat with shorty headers over stock manifolds. Scavenging from primary length is what makes power. If you're not increasing the primary length by a large margin you're not gaining anything.
Richard - How would you rank these cams by original design? I only ask because I prefer to support the manufacturer that took the financial hit on R&D cam specs.
6 degrees of variation on the intake duration and virtually identical. Summit specs on duration at 0.050 seem a little suspect given the high lift and softness down low, but again little difference. Very cool comparison.
Hi Rich: I have a LS 2008 6.2 Yukon engine I m putting in a '37 Chevy sedan. I'm toying with the idea of installing a Truck Norris cam into it this winter. I've seen your videos on LS cam swaps but not much for the 6 liter's. Do I need to adjust the the or change anything else before I put it back together? Thanks
Wow! Thanks sooo much for doing all of this work. Yup...this was THE cam comparison test that, at least ,I was waiting for. So interesting.... Building a 408. I have the bottom end already and you have helped me decide on the cam. Which is any one of them. Maybe 1 of them w go on sale. Haha. Now I have to decide on heads. I have 2 sets of 317 heads so since I have them I may have it milled and I may put in some bigger valves and bowl blend it. What do you guys think? Oh...it's going back into 2500hd silverado
Had a feeling these results would end up that way with equivalent oil pressure, awesome video! definitely some of the best all-around cams for the smaller LS engines
the dyno makes that easy, but I only tune WOT. I start with low timing (like 20 degrees), then adjust AF to something near 12.5:1(the power gains from changes in AF are not very big). The I add timing until it stops adding power (different timing levels at different rpms)
Still waiting on someone at Howard's cams to send over the rattler or the soon to be new competition to this group of cams coming soon that a little birdy told me about lol
Anyone interested in learning about the LS family of engines should definitely subscribe to your channel. I'm in the process of building a gen 3 5.3 and run upon your channel and have been watching your videos since and has guided me in the right direction for me and what I want from my engine. Haven't run across another channel that does as much testing as you and I do appreciate it. Much thanks
What would bring your RUclips channel to the next level is if you put some of these engine combinations in a vehicle and did a hub or wheel dyno comparison with different drive trains. Manual transmission with different flywheel weights, automatic transmissions with different stall speeds. Plus you could take them to the track and show some time slips and have a little fun!! Stop wrenching so much and enjoy the fruits of your labor. Get you a 4th gen camaro and put your big bang 6.0 In there with a turbo 400 and a decent rear diff.and go have some fun.
Richard!! Come up with your own series of cams and I’ll buy all of them. I’m sure others will also haha. It’ll help support you. I just wanna put them away in the corner to talk about in 30 years.
My question is what we’re the fuel consumption rates compared to stock? I guess at about $4.75 a gallon for premium that has to be a concern from my standpoint in a daily driver.
Richard Hi I have one question with cams that have a 110-114 LSA do they give u more vacuum at idle compared to a cam that gives you a 107-109 LSA? If anyone on here has a answer plz can u lmk thank you!
Got 5.3 lm7 with 200k miles. Wanting to cam it for performance. I do I need to refresh rod bearings? New cam rollers? Or do I leave the motor alone just with springs and maybe new rocker arms?
Awesome information!! I just got a gut punch feeling watching you buzz the sparkplugs out with the impact wrench!! OUCH!!! The spark plugs are made of Porcelain!! you wouldn't use an impact on your toilet. I hope Not!!
Is that because you've changed the cams 50 times or what was the cause? I assume you have to retap them, maybe go slightly bigger in size if it's possible.. Not a great working area to do that stuff on.
I would never be shifting at those RPMs... Normally with my 5-speed manual , I'm shifting at 2000 RPMs. , 3000 RPMs if I'm getting on the highway... I think these cams would ruin my low end torque... And my 20 mi to the gallon.... Full-size club cab truck.
the curves hitting so close makes me wonder if something else is limiting power like not a big enough motor or all 4 cams are where the head flow has rolled off. So agree it would be interesting to repeat with a 6.0 and maybe even a well-ported head that keeps flowing more as lift increases (doesn’t roll off).
@@richardholdener1727 yeah maybe not across the rpm range. So a bigger engine might be interesting. Nonetheless a great test and thanks for doing the work. A friend and I are building an LQ4 but with well ported 799 heads and Trailblazer SS intake. It’s for a 6000+ lb Chevy truck. I would use the Truck Norris cam but I’m curious about the buzz on why they don’t publish an ICL-even if I install straight up (dot to dot) I like to check all the components by degreeing ICL. How did you install the Truck Norris in this swap test? Buddy
hello sir first your videos are awesome to watch but i have a question what is the biggest cam i can install without valve spring change or head work on a L99 with good sound and power Thank you.
Whats the BEST 5.3 LS cam for a gbody swap with no other parts needed, JUST THE CAM? my 5.3 was complete and rnning & came out of a 2001 or 2002 avalanche not sure if thats 1 , 2 or 3 bolt timing gears?
Richard, I've watched most of your videos. I don't recall you testing the Sloppy Stage 3. Have you tested it yet? Also, did you check ptv on these cams?
Here's a question for you. I understand large diameter pipes are good for high rpm hp and smaller diameter can be better for that low end torque. Have you tested this? When I look at my pipes I see it's no wonder people lose all their back pressure and poor if they remove their cats. To me it's disgusting and probably a cruel trip from GM. I'm thinking my 02 Sierra with the 6.0 should have no bigger than 2.5 MAYBE 2.75 exhaust after Y'd together. I have a truck motor, not a race car. My truck should rarely see 3k and never see 4k. What are your thoughts? Setup(planned) 6.0, 706 heads, stock truck intake one of the cams from this video, electric fans to open up area for cold air intake, shorty headers.
@richardholdener1727 Sorry, thoughts about exhaust system diameter. I think for a truck, factory exhaust is way to big. I'm planning a cat delete and entire custom exhaust.
What would you need to do to swap a LY5 out and put a LM7 in? Im wanting to buy a crate motor and i dont want to drop another LY5 in and have to delete the dod. Just wondering if any 5.3 would be simple. I have a 2008 silverado.
Would you recommend any of these cams for a 6.2 (LH9) pickup truck staying stock stall? Or due to the added cubes could i get away with something a lil bigger without losing too much bottom end?
I have a Low Buck Truck Cam that does what these do for $179 shipped or I have 1 step up Truck Plus-I think you would be happy with either on a daily driver
@richardholdener question for the daily driver 06 Sierra regular cab shortbed 5.3 long tube headers with a trailblazer factory stall converter its supposedly 22-2400 stall would one of these cams work well for a daily work truck if not what would
I've used the tbss stall and it doesn't like more than 400hp it will burn up quick and start to buck on you and it was really close to 2000 stall on my 2000gmc extcab short bed
@richardholdener1727 I'm not sure if "base circle" has a different term that I am unaware of.. It would be going in a completely stock ls1 with 241 heads?
After swapping cams like that, would the pushrod lenth matter? Reason I asked is cause I never saw u measure the lenth after swapping the cams. Wouldn't a bigger lift cam change pushrod lenth?
So in the end , order whichever one's not back orderd or cheaper?
Exactly
Cheap is where I'm at
Yup 😅
That’s why I got a tsp chopacobra with the valve spring kit when I ordered it only 400 bucks
The 550 lift cams can use cheaper springs

@@truthisweareallgonnadie.Its recomended but the chopacabra is fine with your stock stall converter and stock gears bro.
Would be cool to get idle comparisons to see if they sound any different

@@richardholdener1727when I say "for a truck" I pointing towards low rpm tow anything that won't move power.
@@richardholdener1727this is probably an experiment I'll have to try on my own.
What would you need to do to swap a LY5 out and put a LM7 in? Im wanting to buy a crate motor and i dont want to drop another LY5 in and have to delete the dod. Just wondering if any 5.3 would be simple. I have a 2008 silverado.
not sure on harness, but dod can be turned off in the software
Would you recommend any of these cams for a 6.2 (LH9) pickup truck staying stock stall? Or due to the added cubes could i get away with something a lil bigger without losing too much bottom end?
I have a Low Buck Truck Cam that does what these do for $179 shipped or I have 1 step up Truck Plus-I think you would be happy with either on a daily driver
What is the price difference between them all?
@richardholdener question for the daily driver 06 Sierra regular cab shortbed 5.3 long tube headers with a trailblazer factory stall converter its supposedly 22-2400 stall would one of these cams work well for a daily work truck if not what would
2400 STOCK?
I've used the tbss stall and it doesn't like more than 400hp it will burn up quick and start to buck on you and it was really close to 2000 stall on my 2000gmc extcab short bed
'I feel like I did all this testing for nothing,' lololol.
How would you feel about testing a dual exhaust vs. x-pipe vs. y-pipe vs. the "switch-fire" type of crossover (like 4 y-pipe where two crossover)?
Engine Masters did that already-very minor changes in power, but sound was different
Lol he said "fingers going everywhere"
If I put a cam will my truck pass smog because if you put headers u don't pass smog in California
I don't have emissions legal cams
Do the stock pushrods need upgrading with these cams?.. I saw a few Truck Norris cam "kits" with stock length 7.4 pushrods?
depends on base circle
@richardholdener1727 I'm not sure if "base circle" has a different term that I am unaware of..
It would be going in a completely stock ls1 with 241 heads?
Feel like all the cam testing was already done on flow bench when will there be actual experiments
cam testing can't be done on a flow bench
After swapping cams like that, would the pushrod lenth matter? Reason I asked is cause I never saw u measure the lenth after swapping the cams. Wouldn't a bigger lift cam change pushrod lenth?
only a change in base circle changes pushrod length
@@richardholdener1727 👍💯
Hey Richard, how well would a chopacabra cam work with a turbo?
works well-check out the truck norris video with a turbo-same thing
