The Mac' Attack

After selling my 2008 GMC 2500 I bought this 05' Z71 CCSB with full intentions of building a full-on prerunner. I'm doing a 4wd Long Travel complete with one-off spindles and upper/lower control arms.

So far, these are my current mods

Nelson Tune
Calspeed LT's
K&N Drop-in (No CAI out where I drive)
3" SI/SO 18" Case Magnaflow

Day I got it.

Calspeed LT's - These were fun to put on...

Cut out my spindles - 1.5" Plate steel

Finished cut, very clean and hardly any slag from the CNC

Progression of spindle design and build - OEM on the far left, initial template in the middle, and soon to be new spindle on the right

New Kings! (I've had these about a couple months already, thanks Jess'!)

Last weekend we accomplished a Jig for the CNC and bored out the center for the axle using the Bridgeport'.

Looks bad ass! Looking forward to seeing the finished product.

Awesome CNC workmanship!!!

I love pre runners, lot of machining work but you got that covered!!! Good luck with your project, have a great day!!!

Oh, that's nothin. Just wait until I get pics/video up of us running the spindles in the Mitsu-Seiki 4-axis CNC Mill.

New wheels showed up yesterday!

Cool build, looking forward to watching this one come together.

aaaand more spindles for my buddies truck - a 2000 Z71

Picked up this gem this weekend for a steal - I want to put a carb'd 5.3 in it so bad but I think it will have to settle for the 98' Vortec 5.7 that's sitting in my friends shop... can't beat free. It has an Olds' 307 V8 w/ Turbo 350 and some sketchy fab work. Has a lot of money in parts though, I'll have this going way faster than my 05' Silvy.

Wow that thing looks sketchy, but I am sure you will make it fly like a bat outta hell.

Anyone want to donate a 4.8? The 307 Olds is being pulled soon.

That is a funny pic. Cool as hell though

Whats even funnier was the d-bags in lubbock that thought it was a good idea to try and tailgate me to take pictures. I took it easy on the way home and had it chained/strapped/blocked in the rear so there was no way it was coming off that trailer without a fight, lol. I seriously need a bigger trailer. I would love to do an LS Swap in this with a carb if anyone has any leads on something cheap. For the time being we're going with a 98' model Vortec 5.7.

Not free, but I would think you could find a 4.8 on CL pretty cheap? I want to say there were some down here for $300.

well, since my suspension build is on hold I'll be going back to the engine work on my 05'.

Here are a few cam's I'm looking at, these were suggested to me by an engine builder in Lubbock. I honestly have no idea but was leaning towards the 220R after riding in a truck with one. I'll have a Circle D 3200 Stall to go with it. This is for my 05' CCSB Z71 that I'm building into a prerunner.

224/224 .581"/.581"
220/220 .581"/.581"
212/218 low lift - saw a few deals on used cams (Chevrolade just bought the one I was looking at)

Thoughts/suggestions?

A TR220 will sacrifice a little lift, but allow you to run LS7 valve springs saving you some money while increasing durability of parts. It will also match that stall really well.

I already have a set of LS7 springs too. If I can find a good deal on one of these I'll prob just go with the 220

Not all 220s are built the same. The thunder racing version i believe is more in the .551/.551 lift range. The LS7 spring are good to .550 or .570 or .590 depending on who you talk to. :lol: Darnie1987 has a 5.3 with that same cam and stall on 33" tires and can't get traction to save his life so should be good for you as well.

Cool, well it should go well with my 35's and 4.56's I have sitting in the shop.

With my new job I barely have time to even see my new house, much less work on my prerunner - the Frac industry is going full speed in West Texas. I should have more time to work on it soon though.

Update... the CNC at the machine shop will be available for use again soon so we can finish our spindles. We have all 4 cut out, just making the final dimension cuts and upper/lower ball joint mounts. We have the code lined out to cut out our lower and upper arms, we'll just need a conference call with Jess on setting up our Kings up front.

As far as my drive train up grades, I scrapped the cam idea and donated/sold my stall to a friend for his build and will just be looking for a 6.0 4L80 combo to build up and possibly turbo. Which 6.0 should I go with for the easiest swap and best power options?

If your looking to go turbo I would just go with a 01 up lq4 they are lower compression than the lq9 so it would be perfect for a turbo build.

When ever your ready, let me know.

Updates...

Not sure if I posted this yet, this is the cutout for the rest of our spindles out of some 1.5" Plate.

Looks good man. I can't wait to see it welded up. Quit workin so much and build your truck already.


Wait till you see what we did to Mic's truck this last week.

Hey, I get my company truck this week hopefully... so now I can cut up this one and put all this heavy steel on. :toetap:
