12363230 3.4L rear wheel drive 2.8L upgrade 

$1975.00

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 long-block 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.
