Get a SHARK and call it a day, or you can see how much a dealer wants for a ZHP flash.

You are best of just getting the shark. Look at a couple of dyno graphs, bumping the rev limit to 7K isnt going to earn you anthing.

to earn anything..... umm you must not be very experinced with diffs. if i drop into 3rd at 70 mph im at 5800 and i want that extra 500 to make it a worthwhile gear. you must not understand and no need to explain further like i said i dont want power just long ggear time with my shorter diff

On the street you really aren't going to gain anything by staying in gear longer as power and torque start dropping off around 6k rpm. With that diff ratio and road speed, a shift into 3rd puts you well past the motor's torque peak and thus beyond range for optimal acceleration. Increasing the rev limit isn't going to change that one bit. The only way you might benefit from the higher rev limit is on an auto-x course where it might allow you to stay in a single gear instead of having to upshift on a "long" straight and then downshift again for the next corner. But hey, you seem to be the resident expert on everything these days so do what you like.

There is nothing special about ZHP cams. The answer has already been given on this subject.
