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

I am a fan of 318s I love them I have owned and driven them since I was 16 iv had some extremely stout ones and some duds! My first attempt at engine building was when I was 17/18. I got a 67 318 block out of a 4 door belvedere i left the bottom end original added 360 heads a summit cam some headers and a 340 intake. Granted looking back now I had no clue what I was doing and God only knows what all I did wrong. But I had high expectations for that engine but it was weak! I mean WEAK!! I swear my slant 6 had more pop to it haha. But it ran and I drove it for several years. I have to admit as much as I love 318s i bowed out and did the popular thing and built(ing) a 360 for my dart. After I did the pros and cons vs money the 360 was just a better bang for the buck. I still have a 318 core I plan to build someday. My expectations would be at least 300 330-350 should be obtainable with good heads. The two weak spots in a 318 are the flow and compression If I was gonna build one now I'd probably shoot for 10:1 and a set of speed master pro comp heads and good aluminum intake to match the large port heads with the same .475/.495 cam I have for my 360 project. I think that would make a solid 300 hp and a super fun street car
