turbo nova,

I would like to know what your goal is as far as HP,1/4 mile time & so-on.?
1/4 mile car,top end? daily driver,good street manners.weekend car,strip only,,street/strip,,,etc.. what is more your goals?

Running a big cam will not hurt the 700,if anything, running a big cam will give you less torque at lower RPM's for the most part,, & torque is what kills transmissions,not so much HP.
As far as your turbo exhaust manifold.
A plane log type manifold will work just fine.

Look at this guys stock modified manifold making a lot of HP.

530 hp@5300 and 588 lbs@4000rpms at the flywheel, with 21psi boost and E85.
