I'm suprised the topend is only 82. I hear the 500HP's are 80-81 and the 525 about 84. More weight? Drag from the midcabin?

I need to prop it for 3-5 more mph , thing is i have friends with 525 motor in 290sc it has 535 hp 600 sc motor is 590hp if your run full tanks 4 people i still get a solid 80-82 82mph plus get there a lot faster, my friends with 525 in a 290sc 4 people full tank drop off to 75-76 mph and get waxed from 50mph up to 75mph .
