I have been running the Chevy 396/325HP in Impala's (1968 now 1965) NHRA factored at 325. Just found out same motor, same heads, intake, carb ect is rated at only 320 HP in 1966-1969 Chevelle's? Bigger engine bay in my car maybe worth that 5 HP added? oh, but the Carmaro's 1967-1969 rated at 325 too!

I am asking for the reduction , worth 60 lbs in my Impala. I would then go from 4070 lbs to 4010 in I/SA
