Did ma mopar make 360 non mag blocks post 93?

I made a drill fixture to drill the passage from the deck to the cam bearing, not expensive or trick. Takes like 5 minutes with a 1/4 drill bit about 10" long. I do this quite a bit so we can run the far superior shaft rocker system over the inferior stud mount chevy style rocker system. Plus the Magnum block castings are way better than the old 60's and 70's blocks.

I have to disagree about the Magnum rocker system being Chevy style. It is not. Chevys use a stud which can flex terribly. They ARE certainly inferior. The Magnum engines at least incorporate a bolt down tight bolt mounted rocker system. While they are not as good as the old shaft mounted LA style, they are FAR superior to the Chevy stud mounted rockers. Their only drawbacks are they are not adjustable and they will not stand a lot of lift. But they will out perform a Chevy stud mounted rocker any day.
