The Victor Jr. 454 EFI Series (R and O) for big-blocks are optimized for high performance engines. Victor Jr. 454-R is based on our Victor Jr. 454-R #2902 for rectangular-port heads. Victor Jr. 454-O is based on our Victor Jr. 454-O #2904 for large oval-port heads (1975 & earlier). They are designed for optimized flow and feature extended runner dividers, smaller plenum chambers and unique runner design for better 60-foot times and max power from 3000 to 7500 rpm. These manifolds are especially suited to 502 c.i.d. and smaller competition engines.
