Highest flowing sbm heads?

Besides driving my son's old '15 Scat Pak...... I eye-witnessed a stock 1320 Challenger (6.4 na 485 factory net hp) turn 12 flat WITHOUT traction. Name one other small block mopar from the factory... ANY available to the public... that would even scratch the surface of that time right off the show room floor. A 2950 pound 340 Duster?? 340-6 pack E body?? C'mon, you ain't serious..... The lead-sled at over 4100 lbs would eat 'em for breakfast while listening to blue tooth, watch them disappear in the back up camera and having the air conditioning blowing. But I get it, very few are realist.

that 340 technology is over 50 years old.. the gen 3 stuff is new. Of course there are refinements ….
you should spend your time( if you continue to make such comparisons) about how a 340 can run circles around a Dusenberg…. The technology advancements are comparable.
I could buy a bad *** Gen 3 if I wanted to, and stuff it in something cool. But I have zero interest in doing so, no matter how well it might run.
your confusing old school passion with perceived ignorance of new technology. Most are well aware of the new stuff and it’s ability. Doesn’t mean you prefer it in /on your hobby car‘s engine bay though

Some folks are getting WAY out over they’re ski’s on this stuff..lol
