67-76 "A"-body applications with Stock Front-ends + Edelbrock Victor or Stage 6 cylinder heads:
383-400 B-engines (Low-deck) applications using the Edelbrock Victor or Stage 6 cylinder heads will fit with stock mounts to locate engine. Mounts may require slight shimming for proper header clearance.
440 RB-engines (Raised-block) applications using the Edelbrock Victor or Stage 6 cylinder heads will not fit with stock mounts. A Motor Plate will be required to locate engine. Motor Plate eliminates engine movement and provides a positive method of locating the engine in the chassis.
