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.
