If we didn't have emission regulations , a redesigned closed chamber would have evolved.
The open chamber / smog head would have never been. :D

How about the 87-88 lean burn 318. The first computer controlled engine. LOL They came with a roller cam and Sirl Port #302 casting heads.

So you've build a 500 horsepower 318 which gives you room to talk....?...
Or just the eloquent way you write things makes it seem that way?..

What’s the difference between a 408, a 340 or a 318? If you can figure that out, they all make the same power.

Hot rodders are the great innovators. They make things work that shouldn't. They make things fast that shouldn't have a chance. They win races that shouldn't ever be won. Winning with parts that you'd think wouldn't work. They've done it for decades. The bottom line here is use what works for YOU. It's like yeller rose is always sayin, It'll work if you tune it to work, and he's right. I've tuned a lot of otherwise junky builds to run like balls on fire. Big cammed low compression stuff. Done it with both open and closed chambers, close to and at zero deck and down in the hole. Stock cam builds. You name it. It's all in the tune and each one requires something different but can be made to haul the mail. Is one kinda this or that "better" than the other? I don't look at it that way. Maybe one kinda this or that is "easier" to make power with. Requires less tuning. So maybe that does make it better somehow.
