360 question?

they recommend a 780. i would run at least a 750 but would go with their recommendation on a 780. hell they built the motor and know what needs to be on it.. a 625-650 will be too small for it.. as long as the rest of your combo is matched to the motor and the 780 tuned properly the car will be fine on the street.

that intake looks like a performer rpm to me.
