The completed engine is hands down the best 351 Cleveland V8 in scale. Extensive decals, which perfectly match accurately restored 1/1 scale Boss 351s, add much authenticity. Interestingly, most Boss 351 restorations omit the “351 4V” and “Use Premium Fuel only” air cleaner labels seen here. You would be factory-correct either way. All restorations do include the decal Revell provides for installation on the left vertical portion of the air cleaner assembly.
