call your preferred cam manufacturer directly. Tech support employees earn a paycheck for specifying cams.

What kind of build?
Why an 8000rpm limit?
what 88 turbo?
this better be a transbrake car
Cause an 88 won't do anything at 3500rpm.
the cam usually dictates the rpm range so if you havent speced one yet
Why...
8000rpm
And why do you feel you need to make power at 3500rpm?

Given your target spool of 3500rpm, you'll likely want an intake duration in the mid-220s range (at .050"). Going too high might sacrifice low-end grunt, while too low won't take full advantage of your big turbo up top.

High compression ratio will help to spiff it up.
