2007 Chevrolet TrailBlazer SS

This is not your average 2007 Chevrolet TrailBlazer. This is a serious, long-term custom build with the kind of parts list that tells you the expensive stuff has already been handled. Built around a fully built LSA-based supercharged V8, this TrailBlazer has been transformed into a street/strip-style SUV with big power, upgraded driveline components, serious fuel system support, and the stance to back it up.
Power comes from a fully built supercharged LSA-based V8 featuring a forged crankshaft, forged rods, forged pistons, and ported and polished cylinder heads. It is also equipped with Fuel Injector Clinic injectors, noted as 1,300 cc, though the exact model and rating should be confirmed. The engine builder is listed as “PRD” in the build notes, with the full name still to be verified. Backing the engine is a Rossler-built 4L80E transmission, set up for street/strip use, paired with an Alan Pope triple-disc billet torque converter — the right kind of driveline setup for a vehicle making serious power.
The supporting systems were clearly not overlooked. The fuel system includes dual Walbro fuel pumps, stainless braided fuel lines, and -6 AN supply and return lines running between the tank and engine. Cooling has been upgraded with an improved radiator and brushless electric fans, while the custom mandrel-bent exhaust gives the build the proper sound and flow. This is the kind of setup where the major pieces were chosen to work together, not just added for the sake of a parts list.
Underneath, the TrailBlazer has upgraded upper and lower control arms, coilovers with the brand to be confirmed, Belltech shocks, and stainless braided brake lines throughout. It rides on a staggered wheel setup with 17x11 rear wheels and 20x9.5 fronts, wrapped in Nitto drag radial tires. Per the build notes, roughly $5,000 was invested into the wheel and tire package alone. The tires were described as brand new with approximately five miles on them at the time the notes were written.
The build history is just as notable as the parts list. This was reportedly a nine-year build, extensively rebuilt with very little original equipment remaining. It has been kept indoors since 2012 according to the provided notes, and the engine has been fully rebuilt with upgraded internals. Additional updates include a battery box, new headlights, and new taillights, giving the truck a cleaner finished look to match the performance hardware underneath.
