i guess i'll stick with the 375 horse version because i'm building a daily driver and i'll have to be satisfied running low 13's. I've always seen the 12 sec range as the magic spot for a strong musclecar. Who knows, maybe i'll be satisfied. I'll be running power brakes and a 3.54 dana and the stronger 408
has a duration @ 50 of 239 in. and won't have enough vacuum.
