Before the lowrider guys come after me... 😅

I respect the craftsmanship. The amount of work in this paint job is incredible.

But for me, sometimes less is more.

👇 Lowrider or factory original?

Original GM interior parts from the 60s and 70s were built differently.

Metal reinforced armrests, metal door panel headers, and details reproduction parts still struggle to match today.

Most people would replace this faded carpet. We restored the original color with RIT dye and a pump sprayer instead. 🔥

Save it or replace it?

The 5.2L Voodoo in the GT350 is still one of the best sounding modern V8s Ford ever made. 🔥

Happy Memorial Day 🇺🇸

Remembering and honoring all who served and sacrificed for our freedom.

My grandfather served in the U.S. Air Force during WWII and earned a Purple Heart. My father proudly served in the U.S. Navy during the Vietnam War. 🇺🇸✝️

Most people would never notice details like this. 👀

Original GM door panels used layered construction under the vinyl to create that deep ribbed texture reproduction parts still can’t match. Even the window crank knobs started out clear before aging into that yellow tint.

This Mustang GT convertible sat for years after being inherited from the owner’s father. Now it’s getting a full mechanical and suspension restoration.

Some people would opt to keep the original 289 engine. We're going for a bit more power with a 302.

What would YOU do?

Hot take... White might be the BEST muscle car color!

’66 Impala SS 427 L36
’70 Chevelle LT1 Swap

The body lines pop way harder in white.

Agree or disagree?

Most people would never notice details like this on a survivor car.

Factory 1970 Chevelle carpet, original GM mats, and even the original manufacturer tag still attached. 🔥

Things reproduction parts still can’t copy.

People expect me to daily drive something wild, but honestly it’s just a bone stock 2015 F150 Platinum with a 5.0 Coyote. 😂

Meanwhile I’m over here pumping E85 in California while everyone else cries at the pump.

Most people would never notice this L36 to L72 dash conversion… but Chevy guys will. 👀

Original L72 tach setups are almost impossible to find today, so this 1966 Impala 427 got the next best thing.

Factory vacuum gauge or L72 tach setup? 🔧

First fire up on this 1966 Corvette 427 L72 🔥

60 lbs of oil pressure, no leaks, no issues, and that big block rumble sounds GOOD.

Still dialing in the timing and carb, but so far so good.

Mother’s Day surprise delivery 👀

Just picked up this clean 1970 Chevelle with LT1 power. First start sounds great already 🔥

Not sure yet if this one’s staying long term or heading into inventory, but it was too nice to pass up on.

Happy Mother’s Day to all the amazing moms out there 💐

Special thanks to my wife for always supporting my car addiction 😂

So naturally… I spent Mother’s Day morning buying another one 👀

Final test drive with the family before this ‘69 Camaro finds its next owner.

Let us know, is it one of the best looking muscle cars ever made?

Our ’57 Chevy was our “something blue”… now I’m upgrading it for my wife

LS swap, full suspension, full custom interior… I don’t do anything small

Still mid-build… classic or modern? 👀
