Nice Chevelle, looks like the badges say 454 but it's hard to tell. If so, LS5 or LS6, 4spd or Auto? I used to have a '65 Malibu SS but it's not nearly the same type of car as the '70 is. Back in '65 the SS was more of a trim package than a performance option. The '70 is clearly a true American muscle car.
