The Shocker

Ya give us a call. We can suggest some good parts that will compliment ur truck.

it was an SS. but saw too many with. i went back to stock but put white on the chrome part and black top cover and lower valence. sorry bout the extra late reply. im not on that often

it should have the 3.73 but i may be wrong. Most people on here that have 3.73 and change to 4.10 dont really feel a difference. you have to factor in tire size as well, you dont want to bee spinning excessive RPMs on the freeway or around town. if u dont have the 3.73 u might as well go 4.10s. just my 2 cents

The TR/TSP 220 and 224 r pretty good cams from what ive heard on here. If you get the low lift version which i beieve comes in at .551 u can use the LS6 springs which u can find for 60 to 80 bucks. The only catch would be that u would need at least a 3k stall and 4.10 gears. Iirc the TR220 with 112 lsa would do good if u were to boost later on.

I think that cam may be too big for a 4.8. U could always get one custom specd to do exactly what u want. The one i commented on was a bit smaller in the 244 range.

Oopps i think ive been postin my replies in the wrong area. To answer ur questions right now i have 3.23 but waiting on nelson to install my 4.10s. I think the stick silvys came with the nv3500 and if u check in ur glovebox there should be a tag that gives u the option codes. Search this site and u shoud find out what u have. For info on the T56 ask Quick. Hes a member in here and hes also the one that had the 16+ psi 4.8 . These motors arent forged but with ARP rod bolts a good head gasket like the LS9 and head studs you can do aot to these motors

2 inch coils/2 inch spindles in front, 4 inch drop leafs in back.
the 5.3 made the front drop another inch or so, so i will probably add 1 or 2inch hanger in the back. still need to notch it!

Ya, sure can, that's what we like to do TUNE! Give us a call or email, we'll get your truck set up!
We are in San Antonio, TX

Nice, mine for now just has long tubes ory and a dumped magnflow but im getting ready to get a stage 3 turbo kit from Trick with a T76. One of the members on here has run upwards of 16 psi on a stock block 4.8.

Hey just boost it. These lil 4.8 can take a beating
