Motor Mounts Left vs. Right

Short answer: There’s no “small-block” vs. “big-block” distinction for Pontiac motor mounts — unlike Chevy, all Pontiac V8s (1955–79) share the same basic block size (with minor variants like the short-deck 303 and low-deck 301), so there’s no separate small-/big-block mount.
