I have no clue, bunk rod from the factory is all I can think of. I haven't compared the two dyno graphs yet but in the 402 the horsepower peaks about 5500 and stays right about 500 all the way to 6700 or so and it barely stats dropping off. As for the torque, if I remember it peaked about 4500 and stays pretty steady in the 400 range through the upper rpms. I left the dyno sheet at home. I really need to pick up my car so I can drive it and check things out.

I haven't driven it with the 402 yet. But previsouly I like the way the car felt when it was making 481rwhp. The only reason I did a direct swap of parts to a 402 is I was thinking later of doing forced induction or nitrous, and that would give me a good foundation. They gave me such a good deal that by the time I got a 6.0 block, crank etc...I would have spent the same money on a 6.0 as a 402. I knew it wouldn't make a lot more horsepower, but its got more avergae power like stated above and a lot more torque which I feel like the car desperately needed.
Nice numbers!!!
