I'm onboard with all but the 4.56 gears. I don't understand that choice.

Interested in your choice of 4.56 gears? Trying to sort out a prospective turbo 6.0 setup and have been told to ditch my 4.88 gears. 60e? tire size?

denmah

iTrader: (2)

Well
It has 31 inch tall tires stock, that and 4.56 gears at 6500 in 3rd is like 130 wich is plenty fast for this

It'll make that gutless 4.8 feel good out of boost in this 5000+ lb truck and take some load off the 60e pushing the whole setup around.

We don't plan on land speed racing it so I ask, why not 4.56

ElQueFør

Interesting. Makes me wonder if 4.88 wouldn't be too bad in my setup with 29" tires, the deep MN6 T56 gear spread, and it being a heavy *** truck.

Did this truck not come with dod and vvt and all that crap?

That truck looks like it is in pretty good shape. How many miles are on it and what did you give for it? Don't mean to be all up in your personal business so ignore if you don't want to answer. I'm just curious what kind of money a truck like this would bring.

Correct 4.8 Doesn't have all the bullshit you have to remove !

It took us a while to find one this clean
I think she paid 9k

92,000 miles super clean inside and out

Why such a big cam?

denmah

iTrader: (2)

because all else fails wanted to have it lump a little, the 216 is barely larger than stock, i also agree its a tiny large but oh well, its fun to experiment

i figure no matter how backwards it is we will hit 400-450 tire easily

I've started using Howards cams over the Trick Flow stuff (and I've used a lot of the 2 Trick Flow cams). They're the same price as the 228/230 and you have a LOT more options. There are probably 6 cams in between the 216/220 and 228/230 that ship same day from Summit.

I'm interested to see how this turns out. A cam that big on a 4.8 with a turbo is either going to make great top-end, or fall hard on its face depending on backpressure.

We run a very similar cam in my buddies 48L SAAB AWD and it runs great in a heavy vehicle with good driveability and 113 LSA.

ive wanted to put a kit on my 11 sierra denali but afraid to grenade the trans lol

You need a different trans builder.

yeah i have used it on turbo 6.0 and 5.3's and i like it alot

Can also grab the low lift cams with moderate duration and tight LSA. They retain low overlap to keep turbo stuff happy and sound mean.

Edelbrock 2215 cam was super responsive on my 4.8 turbo 280z and the idle sounded mean.

Howards makes a LS GM hotcam clone that I'm trying on the new build, It's low lift as well and they sound aggressive in the youtube vids.
