HT 3.4
160 Horse Power

Tired of that tired 2.8 V-6 in your S-truck ? It's time for a major upgrade, GM Performance Parts style. The HT 3.4 is a bolt in replacement for the 2.8 V6 in your 1982 - 1985 pickup or Blazer. And it's emission legal in 49 states (Yes, you guessed it, California said no.) But for the rest of us, the HT 3.4 is the best thing going. With 160 horsepower and 194 Ft. Lbs. of torque your truck will feel better than new, and tow better than ever. The heads have large 1.72" intake and 1.42" exhaust valves and combustion chambers that yield a healthy 9 to 1 compression ratio. The camshaft is a high lift, short duration design, developed to produce lots of strong low end torque and mid range horsepower. With .427" intake and .454" exhaust lift, the cam ensures a strong pull to 5000 RPM. Doesn't sound like your 2.8 V6 at all, does it? It isn't, when GM Performance Parts develops an engine we focus on making power. But not power for the sake of power, but power where you need it. For great drivability, towing performance and maybe even a little off road fun. The HT 3.4L, a serious upgrade for your favorite little truck. With 40 more horsepower than your 2.8 V6, why would you even consider rebuilding that old 2.8? The induction system, ignition system, exhaust, emission controls, water pump and other parts required to bolt in your new HT 3.4 are already on your truck. Sounds like a weekend project.
