There are many good choices for power out there, a cammed LS7 or the recent hemi's pretty impressive. I made my motor decision back in 2010 and went with an all aluminum dart 427w, for me the sweet spot between SB and BB. Since then the options for power have really opened up, God Bless America for the recent muscle car boom! About the only Ford BB I would consider would be a cammer, particularly if I knew I was running up against some chevy BB's
