The average 408...

I look online at youtube videos and such of 408 dyno tests and see a lot of 'ported stock head' and 'eddy aluminum head' builds, most done by joe blow or joe blows machine service, and I gotta tell you...I'm not impressed.

when you can squeeze 440hp from a 10.5 street friendly 340 w/ ported x/J heads, but can't get you're 408 to make 475-500hp/torque? somethings wrong. Either these guy's idea of ported means smooth or they are messin something up.
