A high-torque direct replacement for
1996-99 GM full size trucks and SUVs.
If the 350 engine in your 1996-1999 full size GM truck or SUV is getting
tired, GM Performance Parts HT383E crate engine is a great, emissionslegal
direct replacement with loads of torque. Its larger displacement
delivers more usable torque for effortless towing, which may just save
you some gas, too!
The HT383E is uniquely designed to replace the L31 5.7-liter engine in
half-ton models of the Silverado, Suburban, Tahoe, Sierra and Yukon.
Simply swap the intake manifold, throttle body, exhaust manifolds and
other accessories from your old 350 onto the HT383E and install it in your
truck with no further modifications.
With a sturdy, four-bolt main block, a forged steel crankshaft, a smooth
roller camshaft and durable iron Vortec heads, the HT383E delivers the
dependable power you expect from the venerable Small-Block V-8. It even
comes with a new distributor, water pump and other components that
would be replaced during a rebuild.
Breathe new life into your trusted truck with 10% additional power.
