Given your mods, if this is a race only car, MAST (or MSD) intake. Street car, FAST. JMHO

You may need to buy both, install, tune, run, repeat...and see which one runs better in your combo.

Look through this, it's pretty close to answering your question somewhat:

I believe the MAST intake is the best option, but I'm sure your cam was spec'd for the FAST intake, so I'd just leave it alone.
