A more powerful replacement for your
S-truck’s 2.8 V-6!
Your old S-truck has delivered 20 years of faithful service.
It’s time to reward it with an upgrade to an all-new, more
powerful engine. The HT 3.4 is rated at 160 horsepower
and 194 lb.-ft. of torque. That’s an increase of 50 horses
and 46 lb.-ft.! And it bolts right into the engine bay.
The HT 3.4 rejuvenates your truck with strong low-end
torque and mid-range horsepower, giving it increased
capability and towing capacity. It is a direct replacement
for a 1982–1985 S-truck—S-10, S-15, Blazer and
Jimmy—originally equipped with the 2.8L V-6 and
automatic transmission.
GM Performance Parts delivers the HT 3.4 in a longblock
assembly. To complete the engine, you simply
swap the necessary parts, such as the intake manifold
and carburetor, starter, water pump, etc., from the 2.8L
engine. It’s that easy!
After all these years, your faithful truck deserves it.
