Hemi

Those new EFI Hemi's can make well over 500 to the crank with a head/cam/intake swap, plus the new EMS programming will make a bit more. They're incredible engines... the people who say they're "not real Hemi's" can kiss my ***. There's not many modern-day engines that can make big numbers like that with so few modifications and/or without N20 or forced induction... consistently and reliably, that is.
