H3 6.0 Liter Conversions

The Vortec 6.0 liter engine and 4L60HD transmission conversion for Hummer H3

Consists of a new Vortec 6000 6.0 liter V8 engine specially
matched with a factory or a heavy duty 4L60HD
4 speed automatic transmission, and your choice
of either full time four wheel drive or selectable
2 wheel / 4 wheel drive heavy duty
transfer case.

The base conversion package starts out with
325 horsepower and with performance
upgrades and modifications can be increased
to 495 horsepower. The biggest gain from the
conversion is the increased fuel mileage and towing
capabilities which a stock H3 lacks.

Each conversion is completed per the customer’s
specific requests and therefore build time is
approximately 21 days for the H3. This ensures
that each conversion is completed properly and
the vehicle has been thoroughly inspected and
road tested prior to delivery.
