There are some gains to be had with that intake and throttle body. Stock automatic V6's typically dyno'd around 150whp/160wtq. A friend's automatic V6 with the 74 manifold and throttle body made 161whp and I can't remember the torque number, but I believe it was around 170'ish.
The manual swap will net you more power, around 180whp/185wtq. It just depends how simple or complicated of a task you're up for, and how much you're looking to spend when weighing between the two upgrades.
