I bought this can based on your video and I'm glad I did. I did cai, long tubes, 3in exhaust, and Blue Thunder racing tuned it. I'm extremely pleased with the results... Keep up the great work sir.

Really like the content. My son has a 2006 Silverado single cab with the 4.8. Put some speed engineering long tubes, k&n cold air intake, 3.90gears in it. According to my local tuner’s dyno it made 249 rwhp. Those little add ons really woke his little truck up. Hes diggin that Truck Norris cam. Great videos!!

[@NorthernPerformanceCars]

Heck yeah! That’s awesome. Gears alone are such a worthy improvement. Something a lot of guys skip. Id do a gear and stall converter before even doing a cam myself but

[@JoshSmith-ky4pb]

Yea those gears were a major upgrade. It had 3.23s in it before. He wants to take the 22s off and put some Race star 93 truck star wheels on it.

A really good flowing cylinder head/cam/intake is where it’s at then! With the smaller cubes you just have to use rpm to your advantage

The 4.8 and 5.3 tend to put out very similar HP numbers just at different RPM, Torque does vary though.

Makes me wanna spend so much money lol 😂. I’m like damnit should I beef up my 4.8L? Should I get a 6.2L? I have some other projects, but I definitely wanna have a moderately fun daily! My 08 single cab is begging for some love but my inner gear head says put a 6.2L in it and make it rowdy. I also considered the blower option for the little 4.8L. It came with e/fans and 243 heads so compression is perfect for boost. Supercharged vehicles are so much fun to drive, but then again with my lead foot idk that my gun budget would appreciate the boost. Ultimately my single cab has a place in my heart as a super light auto cross truck that can handle the curves! Have you seen the fastlane truck concept ss nnbs truck on KZbin? Things gotta LS7 and it eats mustangs for breakfast 🤤.

[@rudog5305]

Kenny! I’ve got a 2004 suburban that quite honestly feels tired. It has approx 277,000 miles. Does this have the torque management and do you feel some tuning may help offset the fact it feels tired. Does not seem to have any midrange power. It will still pull a little in first but second gear it just drags ass. I know it will never be fast but it would be nice if it were less of a dog.

[@NorthernPerformanceCars]

I’d be looking into clogged cats. Exhaust leaks. Bad O2 sensors. A tune would absolutely help. But if there is an issue with any of the things mentioned. Repair/replacing before the tune would be very wise.

[@shadowopsairman1583]

It does have torque management, do the timing gear and chain, replace the oil pump using a HV unit by melling with correct oil pickup tube O-Ring.

[@captainhomer9199]

Any chance of testing a gen 4 5.3 from 2500rpm up? I recently installed the btr torque cam and was wondering how Norris cam compared. Thanks for the great videos!

I can do that in the future for sure. Btr does have the flywheel graph posted. It is also in my previous video in a couple spots. The torque cam is better from 2,000 and down. It’s rather small.

What's that white crap on the ground? It was 82 here in Florida today. Just curious, what's going from 87 to 93 worth on something like that? I have heard of some people boasting big gains, but have yet to see it myself.

[@NorthernPerformanceCars]

Terrible season has hit us my man. I’ve never seen substantial gains until it is needed. Normally speaking a few degrees of ignition timing and some torque to be had for sure. Normally until it’s needed it’s not a big gain. I’ve seen 15-20 rwhp on cammed ls1’s in the past. Obviously anything higher compression-more overlap cams-boost

You have me leaning towards the bigger cam now. I just thought it would be too big for a 4.8 single cab truck

[@NorthernPerformanceCars]

@@fabtechoma the sound is going to be similar and fall into how the exhaust is placed. I wouldn’t make a choice there. I guess it all comes down to supporting mods. If you have a stock intake. Well a big cam isn’t going to be able to do much at 6,700 rpm. So the combo working well together. Like why the truck Norris was designed for trucks. To work well in a 6,1-6,200 rpm truck that weighs 4,500lbs
