Just did a 134A converson on my 1976 Corvette what are the recommended pressures
25 to 40 psi on low side. 250 to 375 on high side. High side pressure varies significantly depending on ambient temperature and how much air you are moving across the condenser.
If stock fan, idle it up a bit 1000-1200 to get air moving across the condenser for more accurate high side pressures.
