Well… I figured I should just start a build thread. These updates will go in waves as I move into new phases of the build
process. I am on the computer all day for my job and I don't spend a lot of time online for these types of updates. I am doing all of the downstream work in preparation for the engine swap. I am building this the right way from the start.

Thanks,
Tim

The Ride: 2003 Blazer X. Purchased in April 2019 w/57k miles. Original owner, California car with absolutely ZERO rust
issues or modifications. All maintenance records since new. Dealer maintained (for what that is worth). I searched for
one for a while and this was my final choice. It is in beautiful shape!

The Plans: Turn this into a 530hp LS3 powered brute that I can drive anywhere I want with no worries. Car shows, drag
races, autocross, liquor store, etc. Whatever…

Summary: This is my hotrod project. Some people dump a ton of $ into a classic ride, but this is my money pit. Yes, I
will have WAY more into it than it will be worth, but I don’t care and there are no plans on selling this. Before my mom
passed, I told her that if she left me any money that I was just going to blow it on a car. Well… This is my build, but she
helped me to make it happen. Thanks mom!

Work to Date. I have done 100% of this myself (with some friends for the heavy stuff!). It is SO nice to work with all new

Ought to handle and stop good. Should prevent you from tearing the ground effects off at least.

Edit: I'd take that ABS unit off and go find a long bridge somewhere over a deep lake and throw it off right in the middle.

Thanks guys! It DEFINITELY stops, turns and sticks! I literally have about 3 miles on it since the brake/rear swap. I need to get on the phone with Wilwood tech support work out some dragging issues with the rear brakes. Fronts are great!

Agreed on the blocks. I had 3" Billet in there before the rear swap and did a last minute Amazon overnight Belltech kit to get it back on the ground.last weekend. I had the springs re-arched last week and I need to figure out where I want the rear to sit once the engine is in and I have to hook up the lower Caltrac plates and bars. I assume I will need to bring it up an inch.

Not sure what to do about the ABS setup yet. I am just starting to dig into this project. Will definitely need to research the ABS delete option. Would be happy to see that go... I already have the Wilwood proportioning valve. Not at all a daily driver...

Thanks again,
Tim

There's like 3 local to me. lol Now that the leafs are re-arched make sure the shackles aren't close to maxing out.
Couple of shops around here. This is an old school muffler/exhaust shop - $200 total for re-arching/rebuilding and installing bushings.

Agreed on the shackles. Springs went right in with no issues, but I will need to do some checking on several things as I get some miles on it. Will DEFINITELY need some bump stops. I'll cut the old mounts out this weekend and throw some in above the axle tubes. I won't consider a C-notch since the rear will most likely need to come up an inch anyway.

Figured out the rear brake dragging issue. It is a master cylinder pre-load issue. It is a non adjustable part, but I can still grind the tip down. I added a couple of 1/32" shims between the MC and booster and it greatly reduced the issue. I ordered a push-rod depth gauge and will finish this up next weekend.

Old bump stops are gone. New Energy units in place - BIG difference. Got a little carried away with the cutting wheel, but no big deal.

Thanks MM. I appreciate the comments.

I am new to this forum, but not forums in general. Was on the Impala SS forum for years, but have not had a project in a few years. Finally back at it.

I am going WAY overboard, but I only want to do this once, so I figured I would take my time and build it like I want it. Will then continue to "tweak" it until I am mostly happy (will never be done).

Some folks are happy to go out and spend $50k-$75k for a modern hotrod, but I figure I will have $25k (or so) into this thing by the time I am done and should be able to outrun, out-brake and out-handle most of them. And... everything will be brand new. A "semi" modern hotrod and no car payments. :D

Thanks again!

No big news here, but I took the X down to a local paintless dent repair shop a couple of weeks ago and had them remove 18+ years worth of door dings, character marks, etc. These guys are car freaks and were excited to see this thing.

When I dropped it off, there were 10-12 glaring door dings that I looked at every time at walked up LF fender, both doors and tailgate. Once they put it under the lights, the other 30-40 miniature ones showed up that I could not even really see until then! They called my up 2 days later and it was done. I am blown away! This thing is showroom straight! I need to address a few minor scratches that were already there, but wow! They did an amazing job. $700 total and waaay happy! Love skilled workers and new technology!

Pics don't do it justice...
