2007 TBSS 403ci Engine, Custom Cam, Advance Induction Heads

After a catastrophic engine failure, this customer chose to go with a 403ci shortblock. When installing the shortblock, we also installed our custom cam (230/242) along with a slew of modifications including 232ci ported/polished heads from Advanced Induction, an LSXRT 102mm Intake Manifold, and much more. Being AWD we were unable to dyno, but we thought it felt fantastic on the street!

“After engine failure in my 07 Trailblazer SS, I went with PCM of NC, who did a fantastic job of replacing my motor with a max effort 403 ci stroker build. Also added suspension, front drivetrain parts, along with tuning. Truck runs awesome. Completely exceeded my expectations!!!! “
