300HP is very obtainable with the 289. Remember the Shelby GT 350's were 306 HP. They had the iron heads, solid flat tappet cam, single aluminum 4-barrel, better exhaust manifolds and dual points.

With todays technoligy 300 HP a cinch.

The AOD is a popular swap. But it is about 100 lbs heavier then a C-4. I've done a few and it's a good swap. The OD really makes the difference when you're running steeper gears. It keeps the RPM's on the highway "liveable".
