.060 seems an absurd side clearnce, likely to knock if the rod is pushed sideways on each stroke. Some clearance is necessary to allow oil to escape, although the holes in top largely acheive this.
Plastigauge is intended for modern bearings with a definite clearance. Likely to damage a bearing with no clearance. Beware old stock as goes hard. For a stock car unlikely to exceed 50 mph or equivalent paralledl big ends fitted to fall easily seem to work and last just fine.
