I've seen A LOT of posts about making HP with a 318-So why is it so ???

If I were looking to do something pretty basic...... as in retain the stock 318 LA heads......

Shoot for an honest 9:1cr
1.88 intake valves
Minor porting
Pretty small cam/stock rocker gear
Headers
Std Performer (or other suitable used intake)
Good for 300 horse and 450+ lb/ft
