67 camaro, factory ac, I belive to still be R-12. What are the readings I should be looking for on the suction side and on the high side, car warmed up, doors open and running about 2000rpm, when hooking a R-12 guage set?
I am new at factory air.
Thanks for any help

Outside air temp 80*, 2000 RPM, low side 28-30.5 psi, high side 170-180 psi. Outlet air temp.- 39-42 *.
