"Every single 455 we've build, dyno'd and backed up with drag strip runs has made right at, or over 500hp, and pushed whatever we put them into to 11's at the track."
Just to clarify, this is with KRE's UNPORTED aluminum "D" port heads (which have been reported as flowing as little as 235cfm from some sources), and the Crower 60919 Crower camshaft.
With roller cams, and/or ported versions of these heads, the dyno and track numbers have been even better.......Cliff
