radiator question

[losthelegend]

What size radiator do I need.  I dont know what size(HxWxT) or how many cores I need.  I have a 1977 GMC 1/2 ton 4x4 with a 350 motor and B&M 144 blower with an automatic transmission and air conditioning.  Any suggestions would be greatly appreciated.  Thanks in advance for your help!

Just look it up by application.
