NO EXCUSES.
NO ALIBIS.
No Alibi Performance is built around properly engineered street and performance combinations, with Gen III HEMI at the core. HEMI vehicles receive our full performance and engine-build services, while LS/LT and Coyote platforms are supported for tuning only. The goal is simple: power that still starts, drives, stays together and makes sense as a complete system.

Built to leave right — not come back wrong.
Modified cars need more than a parts list. We look at the surrounding systems, verify the health of the vehicle and make the recommendation around the entire combination.
Pre-build health and compatibility review
Measurements where the build requires measurements
Correct supporting parts instead of shortcuts
Leak, fluid and post-install quality checks
Datalog and drivability verification when applicable
How it works
From idea to finished combination.
We do not publish one-size-fits-all prices because labor, parts and tuning requirements change with year, platform, existing modifications and the condition of the vehicle.
Send the vehicle details
Year, make, model, engine, transmission, current modifications and what you want the car to do.
We review the combination
We identify required supporting parts, compatibility concerns, tuning needs and likely next weak points.
You receive a written estimate
Scope, parts, labor and payment terms are documented before the job moves forward.
Build, inspect and verify
Work is completed to the agreed scope, then checked for leaks, faults, drivability and applicable datalog/tuning concerns.
Have a HEMI build or tune in mind?
Send the car, engine, current mods and goal. LS/LT and Coyote inquiries are accepted for tuning only.
