Why are 318's low HP and torque?

I did not read the entire thread but I did read enough to see all kinds of ways to try and get good power out of a 318. IMO there are only a hand full of good reasons to get involved in a 318. 1) You live in a remote area and finding a 360 is too difficult. 2) You are wanting to build only moderate power AND get decent fuel millage. 3)Your budget is very small and you already have a 318. 4) You're going to run in a racing class that requires you to use a 318. 5) You are building a car that you want to keep numbers matching and it has the original 318 in it. 6) You simply want to prove it can be done. With that said, why not simply get a 360? The junk yards and classifieds have plenty of Magnum 360s out of Durangos, P.U. trucks and vans. Find a decent one and change a few parts and you will be miles ahead and likely spend less than trying to get power out of a 318.
