Build 400HP 318

There have been several magazine articles out there on this. A quick Google search and/or a search through the forum archives should turn these up.

Ask yourself which is more important "400 HP" or a "318". If you're starting fresh, a 360 makes more sense than a 318. And if you are looking for a core to build a late model Magnum makes more sense than a mid 70's LA engine. If the car has a running 318 now, the 360 (5.9L) Magnum makes even more sense as you can keep driving the car while you build the engine.
