Every service a fast car needs, under one roof
Dyno tuning, HP Tuners and Holley EFI calibration, carb-to-EFI conversions, engine and drivetrain swaps, custom fabrication, and complete ground-up race car builds — planned as one combination and proven on the dyno before delivery.
Dyno Tuning
The dyno is where opinions end and numbers begin. We run in-house dyno tuning and pull sessions to validate performance — whether we built the car or you did. You don't guess what your combination makes here. You watch us make it.
- In-house dyno tuning sessions
- Dyno pulls for performance validation
- Every Safford build is dyno-proven before it leaves the shop
HP Tuners / Holley EFI Tuning
A great combination with a bad calibration is money left on the table. We do custom ECU tuning and dyno work on the HP Tuners and Holley EFI platforms — the same tune that idles clean on the street pulls hard at the track.
- Custom ECU calibration on HP Tuners
- Holley EFI tuning and setup
- FuelTech platform experience
- Tuning paired with in-house dyno validation
EFI Conversions
Love the classic, not the cold-start ritual? We convert carbureted vehicles to full electronic fuel injection — a car that fires on the first turn of the key, idles clean, and pulls hard every single time, without giving up its character.
- Complete carburetor-to-EFI system conversions
- Fuel system work matched to the rest of the combination
- Calibrated in-house on HP Tuners or Holley EFI
The Nova build on our home page? Its full EFI conversion was part of the same overhaul — see the customer story.

Engine & Drivetrain Swaps
Power is a system, not a part. We handle full engine swaps and everything downstream of them — transmission, driveshaft, chassis reinforcement — so the whole drivetrain works as one matched combination instead of a parts-bin guess.
- Full engine swaps, including 383 stroker builds
- Transmission installs, including TH400
- Driveshaft installation
- Subframe connector installation
Custom Fabrication
Off-the-shelf doesn't always fit — and on a serious build, it rarely fits well. Our custom fabrication work for race and street builds is done in-house, so the parts holding your car together were made for your car.
- Custom headers
- Subframe connectors
- Driveshafts
- Chassis work for race and street builds
Race Car & Street/Strip Builds
This is the whole shop working as one: ground-up race and street/strip car builds engineered for track dominance and street reliability, with no detail overlooked front to back. Engine, drivetrain, fuel system, fabrication, and the tune that ties it all together — one plan, one shop, one accountable builder.
- Ground-up drag racing builds
- Street/strip performance cars — track power, street manners
- Engine, transmission, EFI, and fab handled in-house
- Tuned and validated on the dyno before delivery
We're not the cheapest shop in South Jersey — we're the one that specs the whole combination, builds it right the first time, and proves it on the dyno before you take it home.
Questions we hear at the counter
With a conversation. Tell us the goal — an ET, a class, or the street car you've always wanted — and we talk budget and timeline up front. From there we blueprint the combination as a whole (engine, transmission, fuel system, chassis) before any parts are ordered. Call (856) 498-6386 or use the form below.
We run HP Tuners, Holley EFI, and FuelTech, and we work with Texas Speed & Performance parts. If your setup runs one of these platforms, we can calibrate it and validate it on our in-house dyno.
Yes — dyno tuning and pull sessions are a standalone service. Bring us your combination and we'll calibrate it and validate the results on the dyno, whether the wrenching happened here or in your garage.
That's the norm, not the exception. A recent customer Nova started as a 383 engine swap and grew into a TH400 transmission, new driveshaft, subframe connectors, and a full EFI conversion — all handled in-house as one project. Because we do swaps, fab, EFI, and tuning under one roof, the work stays coordinated.
Every build is tuned and validated on the dyno before handoff. You leave knowing exactly what your car does — not a guess, a measurement.
Tell us what you're chasing
A full race build, an EFI conversion, a swap, fab work, or a dyno session — the first step is a conversation. No pressure, no obligation. Just a straight answer about what your combination needs.
