How do you make the Olds guys AND GM purists mad all at the same time? We may have found a way. 🤣
We’ve got a customer with a ’71 Olds looking for a completely one-off custom hood. They love the look of classic ’60s GM muscle car hoods, but cowls and the traditional 442 forward-facing scoops just weren’t doing it for them.
So naturally… we decided to stir the pot.
We’re taking inspiration from a ’67 Chevelle hood. arguably one of the best-looking and most iconic GM hoods ever, and grafting that style to fit the Olds.
The result? A completely custom, functional, one-of-a-kind hood that looks like it could have belonged there all along.
And we’ve gotta say… this thing turned out FIRE. 🔥

Do it right the first time!

Something that I was thought at an early age. So last week we had a car come into the shop for a touch up repair due to a garage accident. Ironically this was one of the first of many Muscle cars that I can remember as a little kid that my Dad restored (1983) and it’s crazy after 43 years how good this car still looks.

My Dad was big on using the best materials possible and not taking short cuts going through the step to make things last. Thanks to Danny for letting us be a part of this repair and bringing back some really cool memories on how this Hot Rodder grew up.

When pre-fab parts won't work...

This Fabrication Friday we're taking al look at this custom aluminum hood scoop and some headers.
A little aluminum, a lot of tubing, plenty of measuring, cutting, fitting and welding…and probably a few words we can't post on here. 😉

That's what looks like at U.S. 12 SPEED & CUSTOM

Have a great weekend all!

When a ’58 Chevy Apache is this clean, the engine bay deserves more than off-the-shelf.
We custom fabricated these aluminum engine tins to clean up the engine compartment, hide what doesn't need to be seen, and give everything that smooth, finished look. Then they were painted to match that killer paint! 🔥

More on this 52 Chevy Drag Week truck on this
It's starting to look less like a project... and more like a problem for the competition. 😏 The new beadlock wheels are in thanks to our friends at WELD Racing ! Getting to work on the custom rear wing, front grille, airdam/body kit that will make this Drag Week truck one-of-a-kind.

Horsepower brings people together but stories like this are what keep the passion alive.
This dragster was built nearly 20 years ago by Tom Troxell. Though he never had the chance to meet his grandson Tripp, that little boy got to experience a piece of his grandfather's legacy by sitting in a car he built.
Watching him climb in was a reminder that the things we build can continue telling our stories long after we're gone.
