Highest flowing sbm heads?

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
No, you are wrong. I simply offered the OP of this small block mopar head high flow thread an option to a great flowing head. All the bashing came from old timers that get disgruntled for me bringing it in the conversation. But I believe my point was legit, and relevant to the OP's request, so let them attack on... :)
