[quote=OldSubThe oil pressure gauge on a '47 to '53 does in fact only read 0 to 30 while on a '54, the first year the 261 was available, the oil pressure gauge reads 0 to 60.[/quote]
? Around these parts 60 LB gauges showed up in 1953 along with the 235 in 1/2 tons. Those gauges are delicate and any manhandling can disturb the calibration and I would suggest confirming the reading against another gauge.
