Yeah, I'm talking flywheel. Though considering you can get 600 flywheel HP out of a 340 with heads that don't even flow as good as a stock 6.1L Hemi, I think 600 at the flywheel should be obtainable.
Whether you can make 600 HP naturally aspirated out of 6.1L for a reasonable price is a different question entirely.
