AC system pressures

1989 Ford E-150 351, auto trans, FS6 AC compressor, dual air.

64 oz of r-134a.

104 degrees and 35% humidity about 2 inch in front of the condensor
about 2000 rpm, the readings stabilized at 41 psi on the low, and 330 psi on the high side lines.

These seem like nominal readings, not excessive, due to the heat.

Anyone else have any values for their van?

Seems a little high on the high side.
I put an additional Spall fan in front of the evap Helps (reduce pressure) and at 95 ambient it runs around 230 on the high side and 45 deg inside.
