True but 5.3 LS can get 500 hp with just cam and headers, most I’ve seen so far with magnum is 414 hp, magnum is more on par with older 350 vortec, still a great option for us low dollar mopar guys.

400+ on a truck long block with cam and headers.

And makes enough power to have some fun in an A body.

On regular gas, no less.
