426 Hemi

Nothing is the same on any of the race examples now except the name and the records fall because they loosen the definition of "acceptible" or someone finds a way to incorporate more modern technology in parts or machining accuracy. They were cool for their time - but sorry - a Honda VTec makes them look like a dinosaur in hp/in and even back then a well tuned wedge could outrun them and certainly was more driveable on the street. In terms of cost there's no justification for them besides the aura. I've always been a mopar guy, but really the Gen II Hemi is not the be-all-end-all of engines. Simply a cool approach to solving airflow problems "back in the day".

Not entirely correct Moper. The Hemi combustion chamber allows for more compression without detonation which means you can run more timing and or get better performance from crap fuel. The flow issue is the biggest factor in the horsepower edge but not the only one. I've had wedge heads with 2.14 / 1.88 valves so not quite 2.25 / 1.94 and even if you could get the Hemi valves in the head the port couldn't use the difference if you are talking about factory iron heads. I love my big block wedges though. They have torque, street-ability with low maintenance and the 440+6 has a wow factor of its own.
