How much horsepower does a 89-02 truck make?

While countless motorsport applications made use of the factory ’89-’02 rods in engines turning out over 1,000 hp, it’s long been recommended that aftermarket rods be employed in street trucks attempting to make similar power. Reason being, a street application will spend a lot of its time at low rpm (1,500 to 3,000 rpm) whereas a competition engine will live at higher rpm (4,000-plus). In motorsport applications, the combination of low compression and high rpm, along with large turbochargers, leads to less torque being produced (lower peak cylinder pressure), which effectively keeps factory rods alive. The truck shown above made 1,400 hp on the engine dyno with a set of factory, shot-peened rods and survived more than 50 sled pulls before being torn down.

Is a 6.7 Cummins a 5.9?

It’s believed that the 6.7L Cummins is more susceptible to killing rods than a 5.9L due to its larger displacement (bore and stroke) and tick-higher compression ratio yielding more torque production (cylinder pressure). Those extra cubic inches are constantly beating up on the connecting rods and it’s only amplified as you stack power on top of the factory bottom end. Luckily, many reputable engine builders recommend aftermarket connecting rods and a corresponding built engine once an enthusiast ventures into 800 hp territory and beyond.
