Engine builds. Done right, once.
From a healthy street refresh to a 1,200-horsepower race engine — built in-house in Nashville, machined to spec, CNC-ported where it counts, assembled by people who sign their work, and proven on our dyno before it leaves. Every build documented: specs, clearances, torque values, dyno sheet.
What we build.
LS / LT
The backbone of American performance. Stroker combos, forged rotating assemblies, boost-ready short blocks, heads CNC-ported in-house.
Gen-3 Hemi
5.7, 6.4, and supercharged Hellcat engines — from healthy rebuilds to the bottom ends that hold four-digit power.
Ford Coyote
Gen 2 and Gen 3 builds — sleeved blocks, forged internals, and combinations matched to boost or high-rpm NA goals.
Viper V10 & beyond
We've built and campaigned serious Viper power. Other platforms quoted case-by-case — if it's ambitious, we're interested.
How a build happens.
- Consultation — your goal, your budget, your platform. We'll tell you honestly whether you need a build or just a tune and bolt-ons.
- Teardown & inspection — the quote gets real once we've measured what you actually have.
- Machine work — bore, hone, deck, balance — in-house, to the spec sheet your build gets.
- Heads — CNC-ported in-house with documented flow numbers where the combination calls for it.
- Assembly — clearances measured and recorded, every torque value logged.
- Dyno verification — the build finishes on our chassis dyno with a custom calibration and a printed sheet. You get numbers, not promises.
Why in-house matters.
Most "engine builders" outsource the machine work, buy assembled heads, and hope the tuner down the street makes it all agree. Everything on a Carma build happens under one roof — machining, porting, assembly, calibration, dyno — which means one standard, one throat to choke, and no finger-pointing when tenths of a thousandth matter. It's why our 555 twin-turbo Nova put down 1,208 rwhp and why it still runs.
Every engine leaves with its paperwork: build spec, clearances, torque log, and the dyno sheet. If you sell the car, that folder is worth real money. If you race it, it's your baseline forever.
Common questions.
How much does a performance engine build cost?
Honestly: it depends on the platform, the power goal, and what your block and heads look like when we open them up. Every build is scoped individually after a consultation — you get a real quote for your combination, not a teaser price that doubles later. The consult costs nothing.
Do I need a built engine, or just bolt-ons and a tune?
Most cars don't need a build — a tune and supporting mods get many platforms where their owners want to be. The build conversation starts when your power goal exceeds what the stock rotating assembly safely holds, or when the engine's condition demands it. We'll tell you which side of that line you're on, even when it means selling you less.
What platforms do you build?
LS and LT, Gen-3 Hemi (including supercharged Hellcat engines), Ford Coyote, and Viper V10 are our core platforms. Others are quoted case-by-case — if it's serious, call us and we'll talk it through.
How long does an engine build take?
Scoped with the quote — machine work, parts availability, and the build's complexity all move the timeline. What we commit to at quote time is what we hold to, and you get updates as the build progresses, not silence.
Is the finished engine dyno-verified?
Yes — builds finish on our in-house chassis dyno with a documented tune and a printed sheet. You see the numbers the engine actually makes, and the calibration is built for your combination, not a generic map.
Can you install the engine too, or just build it?
Both. We're a full shop — we can build your engine and install it, or build to your spec for your installer. Either way it leaves documented: specs, clearances, torque values, and the dyno sheet.

Tell us the car, the goal, and the budget — rough is fine. Erin or Bajram will scope it straight, even if the answer is "you don't need us yet."
