No dyno chart, but according to calculators, mine is making about 150hp at the flywheel and 125 or so at the ground using dragstrip time sheets. This just what a stock engine should make.
I am using a 3.08 rear axle with a T350 trans and stock 250 engine. My truck weighs 3350 with me in it. I changed from a 3.42 due to highway rpm. I losts some low speed torque, but I gained out on the road. I drive 65 to 70 most of the time so it was a good trade. Rear tires are 235/75 R15 radials.
