Customer build
The Nova that became a dream car
“Huge shoutout to Safford Speed Solutions (Dustin) for turning my car into a masterpiece. The initial 383 engine swap turned into a major overhaul, including a TH400 transmission, new driveshaft, subframe connectors, and a full EFI conversion. Dustin's dedicated countless hours to the Nova, making it my ultimate dream car.”

How a build works
No surprises. Just a plan and a finished car.
Consult
Tell us the goal — the ET, the class, the street car you've always wanted. We talk budget and timeline up front.
Blueprint
We spec the combination as a whole: engine, transmission, fuel system, chassis. Parts that work together, not against each other.
Build & Fabricate
Swaps, EFI conversion, and custom fab done in-house — headers, connectors, driveshafts, chassis work.
Dyno & Deliver
Every build is tuned and validated on the dyno before handoff. You leave knowing exactly what your car does.
We're not the cheapest shop in South Jersey — we're the one that builds it right the first time and proves it on the dyno before you take it home.
