2014 Regular Cab Short Bed Silverado in the shop for FeatherFoot Garage!

If you guys know Austin at Featherfoot.. you know he don’t own any junk!

This truck came in with a misfire on cylinder 8. After going through the basics and confirming the miss was still there, we narrowed it down to the camshaft lobe and lifter roller. And sure enough, we were 100% correct. Cylinder 8 NON-DOD lifter had gone through the cam.

Austin at Featherfoot said, “Let’s make it happen.” So that’s exactly what we did!

We performed a full DOD delete with our full BTR Stage 2 L83 truck cam kit, BTR valve springs, BTR pushrods, BTR lifters & trays, BTR phaser lockout, BTR gaskets, the whole nine yards. Everything needed to do it right!

This truck already had headers installed, which really helps these trucks breathe and makes for a great setup.

This is actually a setup we sell quite a bit, and we call it the “Daily with a Kick” package! It’s SUPER streetable, super dailyable, has just enough tone to let you know there’s a cam in it, and just enough power to let you know you definitely have one!

This truck could be yours! This one is a GOOD one. Only 89,000 miles, power interior, and an overall super clean truck. Get with Featherfoot Garage because this Silverado is for sale and will be hitting the market ASAP!!

Huge shoutout to Strong Speed Works once again for knocking out another flawless tune. This truck runs exactly like it should, and the 6L80 shifts even better!

If you want this exact setup, or something similar, done on your ’97 to present GM V8, get with us! From basic maintenance and repairs all the way up to four-digit power numbers, we do it all!

4.8 TO 6.2 SWAP on this 2004 GMC SIERRA REGULAR CAB SHORT BED!

This truck belongs to a previous customer of ours that we originally built the motor and transmission for about 3 years ago. The truck came back to us running and driving perfectly fine, with absolutely nothing wrong with it. The owner just decided he wanted MORE POWER… And honestly, what can you say? You can’t blame the guy!

This time around, we swapped in an iron-block 6.0 that has been bored out to a 6.2L! It was fully machined and rebuilt by Hodges Machine Shop.

We went through it with:
•GPI SS3 camshaft
•New lifters
•Fresh 317 cylinder heads
•GM headgaskets
•GM headbolts
•Valve job & resurfacing on the heads
•BTR Dual 660 valve springs
•Melling oil pump
•All new gaskets throughout the entire engine
•GPI 7.425” pushrods

And of course… you guys know I’m absolutely terrible at taking pictures of finished products.. But this thing turned out AMAZING!

There’s a video of the truck idling in the comments!!!

We really appreciate this customer continuing to trust us with his vehicles and continuing to support the shop. It’s always cool when someone comes back years later wanting to take their vehicle to the next level!

Once again, a huge shoutout to Strong Speed Works for knocking out the tune on this bad boy!

We appreciate and love every single one of you guys who continues to support us, recommend us, and trust us with your vehicles. None of this would be possible without you!

If you or anyone you know have a 1997-present GM V8 and want this or something similar to this done.. give us a shout! From basic repairs all the way up to your 4 digit power goals, we got you covered!

Absolutely beautiful Sunset Orange Metallic F-body Camaro in the shop!

The owner wanted this car to have that unmistakable cammed sound while still being something they could jump in and drive anywhere. This car sees long road trips, including events like Hot Rod Power Tour, so keeping it fun, reliable, and truly streetable was the goal from day one.

To make that happen, we pulled the K-member, tore the engine completely down, and gave it the attention it deserved. We installed a BTR Hot Rod camshaft, all new lifters and lifter trays, GM head gaskets, BTR dual .660 valve springs with all new valve seals, hardened BTR 7.400” pushrods, Meiling HP oil pump, and all new gaskets on entire engine.. and topped it off with Speed Engineering 1-7/8” long tube headers feeding a 3” catless Y-pipe into a SpinTech F-body muffler while keeping the factory SLP center-exit exhaust out the back!

While everything was apart, we went one step further and refinished the engine in Sunset Orange Metallic automotive basecoat/clearcoat. Not only does it match the car perfectly, but it gives the engine a durable finish that’s built to last. The end result is every bit as clean as the outside of the car.

This isn’t one of those cars that’s miserable to drive. It has an awesome idle, sounds exactly like a cammed LS should, and is still 100% street-friendly. No excessive bucking, no fighting it through parking lots.. just a great-running combination that’s ready to rack up miles and put a smile on your face every time you hit the key!

Next stop is Strong Speed Works to get everything dialed in on the street and then strap it to the dyno and see what kind of numbers this combination puts down. We can’t wait to see the final results!

A huge thank you to our customer for trusting us with such a beautiful car. We truly appreciate the opportunity and we’re excited to see this Camaro back out on the road doing what it was built to do!

If you’re looking for 1997-present GM LS or LT V8 engine repair, maintenance, diagnostics, or performance upgrades, we’d love the opportunity to earn your business. Give us a shout, and let’s build something you’ll be proud to drive!

2017 C7 Corvette in the shop to let this thing finally breathe the way it was meant to!

Over the last few months, we’ve fixed a handful of issues on this Corvette, and this visit was all about taking it to the next level!

The car already had a solid foundation with a Texas Speed Stage 1 camshaft, LT4 high-pressure fuel pump, LT4 injectors, and an MSD Atomic intake manifold. This time, we topped it off with an A&A centrifugal supercharger setup running 6 PSI of boost and made sure every detail was right so the car would perform just as good as it looks!

A stout 688 horsepower to the rear wheels! Huge shoutout to Strong Speed Works for absolutely knocking the tune out of the park. It is spot-on, and this Corvette drives every bit as good as it performs!

To our customer, thank you again for trusting us with your pride and joy. Having customers come back time and time again means everything to us, and we’re grateful to be the shop you count on!

Whether you’re looking to get your 1997-present GM V8 car, truck, or SUV running like new, or you’re chasing a four-digit horsepower build, we’re here to make it happen. No job is too big, no project is too small. Give us a shout, and let’s build something you’ll be proud to drive!

🚨 BIG ANNOUNCEMENT 🚨

This is a bittersweet post to make, but one we’ve been looking forward to sharing…

We’re officially in our new shop!

Last week we took a few days off to get everything moved over, and while we still have a little moving and organizing left to do, the shop is about 98% ready and today (Monday) was our first full day working out of it!

It’s honestly hard to put into words what this means to us.

Four years ago, I opened this business at just 18 years old in our old location. That little shop gave us the opportunity to build something I could’ve only dreamed about. We met some incredible people, built some incredible vehicles, and earned the trust of customers who became friends. I’ll always be thankful for where it all started! None of this would’ve been possible without every single one of you!

Whether you’ve trusted us with your vehicle, recommended us to a friend, shared one of our posts, or simply supported us from the sidelines.. thank you. Your support is the reason we’ve been able to take this next step, and we don’t take that for granted for a second!

This new shop is a huge milestone for us, but it honestly feels like it’s just the beginning.

We’ve got way more room, two lifts, our own dedicated engine build room, and finally the space to work the way we’ve always wanted to. Me and Alex are absolutely over the moon about what we’ve been able to build, and we’re excited to put it to work for you guys!

As we get settled in over the next few days, we ask that you bear with us. There are still a few things to move and get organized, but we don’t plan on dragging the process out. We’re already back to work and doing what we love.. we’re just getting everything dialed in at our new home.

We can’t wait to continue working with all of our loyal customers, and we’re just as excited to welcome new faces through the doors. Every project that comes through this shop means the world to us, and we’re more motivated than ever to keep raising the bar!

From the bottom of our hearts, thank you for believing in us, trusting us, and helping make this dream a reality. We cannot thank y’all enough!

Here’s to the next chapter. We truly believe the best is yet to come!

This clean 2003 Regular Cab Short Bed came into the shop needing a little more than just an exhaust upgrade! The customer had been driving this thing around with long tubes only for way too long, so it was time to wake it up!

We hooked it up with:
• GPI Stage 3 Low Lift Truck Cam
• Brand new lifters & GM lifter trays
• Melling high volume oil pump
• Fresh engine reseal with all new gaskets
• Freshly milled 243 heads from Hodges Machine Shop
• BTR valve springs, valve seals, and pushrods
• E-fan conversion using factory 05-07 harness

And let’s be honest… we couldn’t put the engine back in looking dirty. It got a fresh coat of black with cleaned up aluminum accents. You just can’t beat that look!

The customer also wanted us to address the transmission since this 4L60 had definitely passed its life expectancy… (3-4 clutches were somehow still alive). So while it was apart, it received:
• TransGo HD2 shift kit
• Heavy-duty high-energy clutches and steels
• .500 boost valve
• Corvette servo
• Extra wide band
• Heat treated sunshell
• All new gaskets and seals
• Mishimoto 40K transmission cooler
• 3200 stall converter

Of course, spinning one tire isn’t cool anymore, so we took care of that too. We installed an Eaton TrueTrac along with 3.73 gears, replacing the factory 3.42s to give this truck a little more pep in its step and make sure it’ll leave two black marks instead of one!

I completely forgot to take a 100% complete photo, I can’t believe it either! lol

Huge thanks to Strong Speed Works for coming out and laying down an awesome tune that really brought this combo to life. This truck finally sounds as good as it runs! It’s a very impressive daily driver combination!

Most importantly, thank you to our customer for trusting us with your build. We appreciate every single person that lets us work on their pride and joy!

If you or someone you know has a 1997-present GM LS or LT powered truck, SUV, or car, we’d love to help. Whether you want to bring your daily driver back to life, build a reliable street truck, or chase four-digit horsepower, we’ve got you covered. No shortcuts, no guesswork, just quality parts and quality work!

BIG ANNOUNCEMENT COMING SOON… Stay tuned! 👀🔥

Insanely clean 2018 High Country Silverado back in the shop for a little change of pace… and a whole new heartbeat!

This truck rolled in with a Texas Speed Chopacabra cam kit, but this time around we stepped it up with a BTR 225 full cam kit. We also installed:
• New lifters
• New lifter trays
• New pushrods
• LSXceleration ported L86 cylinder heads
• Manley stainless valves
• BTR Dual 660 valve springs
• New LS2-style timing chain
• New cam phaser (the original one came apart… thank God for the safety bolt)
• New oil pan pickup tube O-ring
• New oil cooler O-rings
• CHE trunnion upgrade
• ARP crank bolt

We’ve had the pleasure of working on this truck before as well, installing a Circle D 3200 stall converter, long tube headers, and a catless Y-pipe, so it’s always awesome seeing customers come back when they’re ready for the next round of upgrades’

This thing absolutely sounds mean. Without a doubt one of the best sounding truck exhaust setups we’ve heard in a long time. It runs as good as it sounds, and we couldn’t be happier with how it turned out!

Huge thanks to Strong Speed Works for putting the finishing touches on it with an awesome tune.

And most importantly, thank you to our customer for continuing to trust us with your truck. We truly appreciate the repeat business!

Whether you’re looking for a full cam swap on your ’99-’18 Silverado, performance upgrades, or you just need your daily driver back to 100%, we’ve got you covered!

No job is too big or too small. No horsepower goal is too crazy, or too modest. Give us a shout and let’s build something you’ll love!

It is that time of the year… It is DOD delete season!

As crazy as it sounds, every single year when the weather changes, whether it’s cold to hot or hot to cold, we start seeing an absolute flood of DOD lifter failures come through the shop. It happens every time and this year is no different.

Last week alone we completed THREE full DOD deletes, all three being L83 5.3L’s. Every single one was knocked out flawlessly and executed exactly how it should be.

What’s even crazier is two of those trucks had already been told they needed COMPLETE NEW ENGINES.

They did NOT need new engines.

They had lifter failures.

Do not get roped into the “it needs a whole motor” scheme before having somebody who actually specializes in these engines look at it first. We fix these trucks every single day. These failures are extremely common on GM LS and LT platforms and properly diagnosing them matters.

A loud tick, misfire, check engine light, collapsed lifter, bent pushrod, low cylinder contribution, excessive valve train noise, all of that does NOT automatically mean your engine is junk!

WE SPECIALIZE IN 1999 TO PRESENT GM LS AND LT V8 ENGINES IN ALL GM CARS, TRUCKS, AND SUVS.

Why take your vehicle somewhere that occasionally works on these platforms when you can bring it to a shop that lives and breathes them every day? We know these platforms inside and out because this is what we specialize in, day in and day out!

Whether it’s stock daily drivers, work trucks, performance builds, cam packages, DOD deletes, turbo setups, diagnostics, tuning, or complete engine builds, this is what we do!

We appreciate every single one of you that trusts us with your vehicles. The amount of support you guys continue to show us does not go unnoticed and we truly cannot thank you enough for it!

If your GM Car, truck, or SUV is making noise, misfiring, ticking, dropping cylinders, or somebody already told you it needs an engine, give us a call before making that decision!

Extremely clean 2000 Chevy Silverado 1500 regular cab short bed 4x4 V8 in the shop this week! Owned by the one and only FeatherFoot Garage!

For you guys that know, these trucks are getting hard to find… and finding one this clean? That’s on a whole different level. What makes it even crazier is this truck is sitting at 300,000 miles, but you’d swear it has less than half of that!

Initially brought it to us because the truck lost all gears, but After digging into it, we found the issue. Every torque converter bolt had broken out of the converter, taking the threads with them and were just bouncing around inside the bellhousing. That ended up taking out the rear main seal and even cracking the oil pan.

So we went ahead and gave it what we like to call our “keep oil inside the engine” upgrade!

We pulled the motor for proper access and went through it the right way:
• Replaced the damaged oil pan
• Installed a Melling high-volume oil pump
• New TMBX torque converter
• Rear main seal
• New valve cover gaskets
• New timing cover gasket and front crank seal
• New water pump gaskets
• New spark plugs
• Extracted all broken exhaust manifold bolts
• New exhaust manifold gaskets
• New intake manifold gaskets
• EGR delete and blocked off at the intake

Put it all back together the way it should be so this thing is ready to go another 300k

Huge thank you to Austin for trusting us with this truck, we appreciate the business as always!

If you’re looking for a super clean older (or even newer) Chevy pickup, get with featherfoot garage and shoot him a message, tell him we sent you!

And if you’re needing work like this done or want to give your truck a fresh start, don’t hesitate to reach out to us. We’ve got you covered!

Here’s one you guys haven’t seen in 2 1/2 years!

This is MY personal 2005 GMC Sierra 1500 RCSB 4x4 truck. But it is at its best now! Last go around, it was a 6.2L ls3, cam, stall, & 80mm turbo. It was fast but not this fast!

Now it is a:
- 417ci stroker LS3
- Callie’s 4” forged crank
- Callie’s extreme forged rods
- Diamond flat top forged pistons
- Cam motion custom grind cam
- PRC 260 LS3 heads
- .040 head gaskets
- twin 62/62 precision Turbos
- factory 07-13 L92 truck intake for the haters

It made 1,016rwhp on 18psi!

This truck is an absolute trip! And I can’t be more pleased with how it’s running!

Huge thank you to Strong Speed Works for spending the late nights helping and tuning in this bad Larry!

**THE SMOKE IS THE BREATHERS NOT BEING HOOKED UP, I COULDN’T GET IT FIXED BEFORE THE DYNO, ITS FIRST TO GET FIXED!!!!**
