The 361 was the smallest of the Mopar big blocks. It was of the 361-383-413-426-440 series, however, it was never considered to be a high performance engine, as it never received the multi-carbs, crossram manifolds, and high-lift camshafts the bigger engines received. It was though, a bullet-proof, day in, day out engine. This particular fender badge was found on a '63 Plymouth Fury.
