your dream car awaits

we provide THE HIGHEST quality ls swaps to quickly and affordably convert your vehicle to modern ENGINE technology and reliable operation

. . . so you can enjoy your 1974 model year or older car or truck the way you've always wanted 





We carefully research, select, plan, negotiate, repair, buy, install, and service

all of the below components & systems that may be involved with an

LS swap for 1974 model year and older cars and trucks 


crafting a vision & scope

This is where we discuss together what you're looking for.  Do you just want to make a nice, reliable daily driver?  A high horsepower monster?  A killer, high-torque quarter mile eating machine?  And, we talk about the scope of the build.  Do you just want to replace the engine?  Do you want to add a supercharger?  How about the transmission?  Other driveline-related parts?  We have done, and can do, it all.

developing a build plan


Based on your vision, we'll develop our recommended build plan.  It will include our estimated labor cost, a parts list, including manufacturer and supplier names, as well as costs and estimated timing.  We typically aim to complete an LS build in fewer than 4 weeks from the time the engine bay is stripped, depending on the complexity of the conversion.

executing on the build plan

During the duration of the LS swap (and whatever other services you may have us do), we communicate with you regularly to advise you of the latest status and ensure that you feel comfortable with the progress.  You're also always welcome to stop by and see for yourself, in person, how things are going, to see your vehicle, and to chat with us.  We aim to take the stress and worry out of the process for you.


We strive for your 100% total satisfaction.  We'll work with you to make sure everything meets with your expectations and our agreement.  If something's not right, we'll make it right.  We hope that the LS swap is just the first step in our providing for your automotive needs.  We're here to help with whatever future repair and / or modification needs you may have.


One of our customers has been coming to us since 2009 with his first-gen classic Chevy Camaros, four of them in all.  His latest one, a '69 Camaro, was giving him loads of grief.  While it was a powerful V8 engine, it leaked oil continuously, despite getting a massive re-build, and in the end, it was smoking badly and could hardly run at all.  Desperate to enjoy his vehicle, but on the brink of selling it due to his frustration, he turned to us to execute a complete LS swap.  At the same time, he turned to us to narrow the rear end, enabling deeper dish wheels and a more powerful stance.
