A925 4-Valve DOHC Hemi
After getting smashed by the 426 Hemi, Ford when back
and came up with the over 600-hp 427 SOHC "Cammer".
The guys at Mopar caught wind of this plan and started to
work on something to counter with -- the DOHC 426 Hemi.
The powers to be at NASCAR did away with these engines,
so we never got to see them fight it out on the race track.
Let me know if anyone else has some more info on these!
