Why are 318's low HP and torque?

Chryslerkid I wouldn't get to caught up on compression from what I understand the rule of thumb for CR is for every point of CR is +\- is 4% Hp. So let's say you take a dead stock 150hp 2 barrel 318 with 8:1 CR and bump it up to 13:1 CR that's 5 points increase of CR which is 20% increase of hp which would be 30hp increase which a high flow exhaust could easily accomplish. Now let's say you got a 300hp 9:1 318 going one point up or down would only increase or decrease your power 12hp (4%) so 8:1 288hp and 10:1 312hp. Higher compression makes hp through more efficient use of fuel & air but the path to more hp is more fuel & air per rpm. Air flow in and out of the engine is gonna make more power per dollar than compression especially on a medium performance engine. As long you got over the minimum amount of CR for your cam choice and not over the amount of CR for your fuel requirement it's more wise to spend your money elsewhere. Also if you never intend to rebuild the bottom end then mill away but the heads will only be good for a low CR short block if you wish to install KB's later it will raise the CR too much so the heads will become a One Trick Pony.
