Well sometimes disaster strikes.
Our good buddy Scott’s Camaro started to spin a rod bearing early this spring. We hoped it was lifter noise but couldn’t have been lucky enough!
He’s one of our favorite guys so we pushed it to the front of the line for removal. That way it can get to the machine shop and in line!
Now to make it a 383” and some extra torque!!

Pulled an all nighter and even made it in on time to bust out the final welding on Mike’s exhaust.
I love the finished product when doing fab jobs!

He had some tubing from 2017 and damn it shows in the difference in welding compared to the stuff of 2025/2026!

Onto the next!

It’s getting harder and harder to to finish these fab jobs. They just take so long with normal day to day operations. But they sure are sweet when they hit the finish line!

Rob came and picked up his 404” today and dang she looks good!

Guys we are slammmmed right now! This might be the busiest we have ever been and we are doing our best to work through it. Please be patient and expect a bit of a wait on fabrication, engines, and install.

As per usual. Out tuning schedule we will only schedule out 2 weeks tops! So call when you are ready! We are back to messages every 2-3 days!

My buddy Jordan from &cgarage to get his new 408 tuned up in his holler terminator. Such a cool rig.

You didn’t have to hit us with a drive by bird flipper whoever you are 🤣

Anyways, I am in the office today doing call backs and scheduling until about 4 and have to head to the Dyno.
It’s not that we don’t answer. It’s that we have 40 cars on the property at all times to attend to. We have people waiting months and all we can do is delegate time wisely to what we have on our plates. We have done this for years and it has worked well for us. People with patience always get taken care of. It weeds out the impatient - non loyal people.
There are plenty of shops out there. We are not a fit for pushy or rude people. We can’t and won’t drop what we are doing at all times. Anyone that has done business with us knows how this goes and never has an issue. It’s always new people.
So I make these posts here and there.
If you can wait your turn we’d love to help you! Super simple! If you call and we don’t answer. Shoot us an email or message on Facebook.
We always respond, even if it takes a bit.

Been a while since we’ve had an 07-13 in here! This one is a local truck in for a dropped lifter. Btr stage 1 truck cam going in with the dod upgrade service!
Joel has his excited face on as well! (I’m just kidding. I’m not sure why he looks so pouty 🤣) bad photo timing I guess.
