Stumbled across this looking for something else.
https://www.hotrod.com/articles/build-reliable-powerful-ford-y-block/ Not a performance build but it looks like they actually did talk to people who know, first.
One thing that seemed ignorant to me is "The Ford Y-block is a stodgy old cast-iron American V-8 that has taken a lot of research and development to produce respectable horsepower and torque at the Engine Masters Challenge." It is valid, but they make it sound as if all other engines were just power monsters right out of the gate and did not require any development, that they haven't had or needed the decades of development they actually have had. The Y is just playing catch up. That's a small gripe. Seems to be a good article overall.
