What cam did you go with, why, and do you like it?

[mikeyss]

I went with TSP VVT-1 cam and I absolutely love it. There is torque all through the powerband, and after 4500 RPM it feels like the front end gets light. All I need are flaps and I could probably fly! Also, driving in the Rockies with this cam, almost makes my 6.2 feel like a diesel pulling.

Always love when you chime in, Dave I'm a nerd so I want some chop chop choparoo

I had no idea Holdener had his own cam grind! I love the chop, too, and definitely want and aggressive idle.

I think with the 4.11's and the deep gearing of the 6L, it'll spend more time in the higher RPMs.

Drive it like ya stole it! I'm the same way, usually driving like I'm running late, even if I'm half hour early. Mine sees over 4k daily with 3.08 gears I'd imagine it's going to see it more often with 4.11's. This thing is an absolute pig unless you stomp on it, due to the gearing. I did the math on final gear ratios with 3.73 and 4.11, and I like where the math puts 4.11's. It essentially drops 3/4/5/6 all down to the next gear down (IE-4th will behave like 3rd does now, etc.). ANYTHING will help the city mileage, as currently you have to put your foot IN it to get it to start moving.

I've debated doing the Truck Norris cam, too, but I'll be doing springs either way.

It's getting lifters, springs, pushrods, seals, the works. Mine's got 243 heads, so I'm thankful for that.
The 109° LSA is indeed tight on the Stage IV, but even the Stage I is a 112°. I mean hell, the Truck Norris is a 107! Now, I could look into TSP's low lift cams, as they're a 111° on the stage 3, or 112° LSA with 3° built-in on the stage 4...
I just don't think that the low-end is going to be an issue with the loose converter.

Time to do some more digging. Thanks for the input fellas!

He (Richard Holdener) was selling several versions of his Low Buck Truck cam. One was an NSR version, one was the regular version (my purchase, which required upgrades valve springs), and a high-lift version.

I don't know if he offers the NSR or high-lift versions any more, but you can email him directly at: [email protected]. (He posts this contact email in most of his YouTube videos & live streams, so I'm not doing him.)

You can also comment in his live stream chat, and he'll talk to you in real time. The BTR Truck Norris cam had always been on my radar, and when RH started selling them for $169 my monkey-brain had no choice but to buy it.

Can you link your product webpage here? Whenever I search for my year/make/model the TSP website directs for Godzilla 7.3 cams.

Did you have to get a tune after installing the cam?

I just did a little snooping around on the cam motion stage 2 and I like what I’m seeing. I want to wake up my 4.8 just a bit

Yessir. Blackbear did the tune for me and they did a great job.

Thanks that was my next question…

I’ll add it to my Christmas list. Going from 6.0 to 4.8 leaves a lot to be desired. Maybe the cam will help.
