Factory old iron just can't compete ... ??

See, I never even look at modern engines for high hp. What’s the blow apart rpm on a new hemi? 6500?

I love the modern fuel injection and drivability. If these hemi engines last 50years then I’m impressed. I know my 6.4 liter hemi in my personal work truck at 147k does not even go thru any oil. Runs like a beast. Well near oil change time I have to add 1/2 a quart. That’s about 5,500miles.
Sorry OP: I got side tracked.
Back to you…
