on just motor it made 311hp uncorrected.... 303hp corrected and 338tq at the wheels motor is bone stock only bolt on mod is a homemade intake open exhaust no programmer
i'm not sure why power dropped in the higher rpm the a/f was getting better at 5300rpm a/f was 12.4 to 1
this is a truck not a car........5000 pounds
