modified firing order big block

Wasn't there an early Hemi that had that? Had these huge trumpets on the exhaust...lol

Not factory. You are probably thinking of the old Mopar "High n Mighty."




Any engine can be set up with something like dual throat webers, that is if you can get an intake or build one to fit them---- to provide a barrel for each cylinder, and nowadays, some are modifying older Hillborn/ Enderle injection for EFI. That with individual header tubes in effect creates 8 separately tunable independent engines, but of course exhaust systems are a "little tough" and many race classes require collector headers and or an exhaust system.
