Copying from the HotRod Article:

Why build a 318? Some may argue there is never a reason to build the Mopar 318. When the time comes to rebuild a small-block, the 318 should always be cast aside in favor of a 360. We won’t argue. A 360–built properly–will always have a torque advantage over a 318.

Does this sound familiar around here ?, lets continue:

However, 318 cores are free for the asking, and that offers some economic incentive. But the real motive usually isn’t a matter of cost. The bottom line is like it or not, 318s are being rebuilt by enthusiasts every day. Some guys have a certain sentimental attachment to these cute little engines. sometimes it’s just the desire to retain the car’s original powerplant. And some guys dig the idea of blowing doors in with just a 318. Count us in that last group. We were intrigued with working out a combo that shows how to really make one run. Our goals were straightforward:



-The engine would be based on a regular 318.
-The engine must run on 91-octane pump gas or less.
-The camshaft must be daily-driver streetable, at least in a hot-rod sense.
-The build will not include any exotic, rare, unusual, or excessively expensive parts.
-The parts will be bolted on out of the box with no custom tricks, massaging, or porting.
-The final output would break the 400hp barrier.

and goes on... to THE BUILD.
