Nick's Garage dyno's a 318 Stroker.

Thinking a 318 needs a stroker kit to make 350-400 hp is a mistake. And in a race to 400 hp, at todays prices, starting from scratch, the 318 is still the better buy on the pocket book than a 340. And 318's have roller cams from about '85 to 2002.

And if looking for 300 hp for a Dairy Queen cruiser, the magnum 318 (sorry folks, it's still a 318 with a 3.31 stroke X 3.91 bore X 8 cylinders) will get you there lock, stock, and barrel for about 500 bucks (that includes buying the engine :D)

And while I'll say the 360 magnum is the best bang for the buck in the small block mopar world, the 318 magnum is probably the next best choice.
