Quick hit to 6300 RPM

It will smoke the tires quiet easily too

Did you notice any loss on the low end?

With any camshaft in most cases you're gonna give up either some bottom or top. When I was running the SS2 my 3200 stall, 4.10 gears and 29.7" tires overcame a lot of the low end torque issues I also have a reg cab short bed. With a heavier vehicle, taller gears, larger diameter tires and less stall the bottom end will be more soggy. If you're not going to rev the engine to 6000+ RPM on a regular basis I would look for something else.

In the first video I posted you can see the tach around 1550 RPM when I went WOT. It revved pretty quickly with my combo BUT I was on a slight down grade on the hwy too.

If your Price Shopping SS2
If you want more top end SS2, But you will trade off with less power below 3500
If you want an all around cam with little trade off. BTR Truck Norris

Plenty of dyno sheets and comparison including a stock cam. This shows the difference between the 2 and even a stock cam in the first half of this video before they add boost.

Meanwhile since this threat started, @Summitracing has released their Big Truck Torkinator.

Damn, now we gotta wait for Richard H to do a dyno shoot out with the new cam versus Truck Norris.

I just finished tuning a 6.0 with the truck norris in a 2500hd and it really didn't seem to make much difference till rpms were above 3400ish.
below that the tune didnt need hardly any fueling adjustments. It seems to pull up around 6100-6200 rpms amd flattens out.

I feel like the regular ole 212/218 cam with a 112 or 114 lsa is more useable. Was expecting the 107 lsa of the TN cam to make more low end TQ.

Does it seem like the 6.0's really eat up most cams unless they're pretty radical? I have a few guys locally selling some 212/218 and 216/220 cams for pretty cheap.

Also found a tci 2800 stall here local for only $400. Never used.

Talked to Glenn's performance. He recommended the tsp stage 3 216/220 .550"/.550" 112 LSA. I think that's the cam I'm gonna go with to keep the factory stall for now
