360 Magnum vs 340 mild street build - my experience

The only argument you will get from me, is Chrysler designating them as Magnum engines. lol
The true Magnum engines died over 50 years ago.
Sure would have been nice if Chrysler built a big block roller engine for trucks.
I can't see any reason to build anything other than a modern 5.9 or 5.2 if you're building a small block.
