Just so you have the dates of brand-x vs FE in perspective

"Chrysler pegged its efforts on the recently reborn Hemi, Chevrolet relied on the 427 big block “Rat Motor”, and Ford used its 427 “FE” series engines. That scenario put Ford at a bit of a disadvantage because the “FE” was a dated design having originated in 1958; the 426 Hemi debuted in 1964 and the big block Chevy first hit the streets in 1965."

That "dated design" sure has whooped its share of Hemi's and BBC's

And thats not accounting for all the Ford parts that NASCAR outlawed...Hiriser, cammer etc. Let alone that MOPAR was allowed to run the midsized Dodge Coronet and Plymouth Belvedere with their Hemi. Chrysler even stated to Bill France they could not win using their full size Polara or Fury bodies against the Galaxies.
