Thanks for running this test. 10 years ago I did a cam only swap in my 2005 GMC 1500 Truck with the 5.3 L LM7 and selected the Crane Cams cam #1449541 Grind No. HR-200/2951-2S-15 1 A, 200/208 degrees at 0.50, 502/502 lift, I think it was on a 115 LSA. (I can send you the cam card) . I choose this cam because is was better torque adn HP over the entire rev range. I found this cam in a magazine article. I want to put this same cam in another LMF in a truck nut Crane is no longer in business, and I cant find a similar cam at Comp Cams. TruckNorris is giving up torque down low and that does not work for towing my boat. Have you tested this Crane Cam? in the 5.3 LM7.

[@stevenspeckmann2075]

Can you test this cam with a y pipe and single muffler? I’m curious if it would change that low end torque

[@exploranator]

As far as I can tell, a turbo just acts like an engine size addition once it spools up. If you have a cam that emphasizes the low end, it will spool up more quickly, but the new power curve will still be (spooled up boost extra power amount) on top of and kind of parallel to the original, naturally-aspirated power curve. Theory: Now, if you are patient, you can put a large enough turbo on it that by the time it spools up, it will be up near redline, so a rising boost curve like a centrifugal supercharger will result, with easier exhaust flow and less backpressure. The beauty of the centrifugal compressor is that it has so many options surrounding it.

[@shadowopsairman1583]

Bear in mind the area inside the intake system, hair has to fill it up. To spool a turbo either you use a tiny turbo or a super charger

Unless you have a rare (these days) manual transmission, then no it's not the magic number. Any automatic will unlock the converter well before you start "grunting" to prevent the converter clutch from burning up.

Truck norris cam is just a 112-114 torque cam with high lift on 107 Lobe Center. This will have more overlap and lope than usual cams with 112+ lobe centers like Crane cams in 1980's had 112 lobes with low compression ratios of that time Competition Cams Created the High Energy Cams with non symetrical Fast open slow close hydraulic ramps and 110 lobe centers. This added more effective duration and overlap boosting power at the top the tight lobe center makes strong mid range and more cranking dynamic compression while having lower torque cam duration specs its a torque cam on tight lobe centers high lift for more dwell time beyond peak flow or stall in stock cylinder heads. Should make a nice street cam w/o loss of vacume lopey idle strong bottom and mid with good top end.

What do you think about E 85 for my stock LQ4 I’m in SLC is it a hassle to buy to run in my car. I’m doing a ground up build and I have the bigger fuel pump with-8 PTFE fuel lines

Looks like the factory cam in my 04 2500HD is the right cam for me, probably 98% of my driving is sub 3000 RPM.

Its nearly impossible to gain anything noticeable under 2500 over a stock truck cam. Car cam yes, truck, no. I don't drive around flooring it everywhere.

So when I did the cam swap no issues with the motor but I used LS7 lifters first and I used new trunion upgrade from Michigan Motorsports. I found 2 collapsed lifters so I too all the LS7 lifters out and went to stock Melling lifters but ever since the cam I get weird tick but it’s all the rocker arms. Does anyone else have this issue? 6.0 LQ4 , Truck Norris Cam, Stock pushrods, trunion upgrade stock lifters.

Have you done this with turbos? Does it matter how long the exhaust is after the turbo? With mufflers?

[@aaronmartins4077]

Does an x pipe change anything? Does an x pipe on a modified LS make a different power curve than a stock LS? I was curious how that longer tube plus muffler made a dip, if an x pipe or h pipe would increase the loss, or make a gain?

I have a 07 5.3, i considered this set up...but Im concerned about having to do the cyl cancellation along with this cam pkg I would like a lil more towing zip but Im afraid of sacrificing fuel mileage. the truck already is sorta a pig on fuel now in stock form Anyone have real world experience with this set up as far as that? I also wonder if it would pay a guy to just put a junkyard 2014 and up stock motor in his truck as they are rated I believe at 360 365 hp stock. Richards combo here made 400 hp but its modified and bored bigger.

What are the specs on the Truck Norris cam? Heard so much about it, and the power curve is awesome in how it just hangs close to peak power for 1000 rpm. Hard to miss gearing with an engine like that. But that engine should be awesome with Mast heads and 2.08 intake valves. That's about maxed out for a 99mm bore.
