Oil Cooler Questions??????

I have just finished/started my build up. Its never really finished anyway, right? I built my 305 up to a 334 with the help of a good crankshaft and a great tech here in Oklahoma. Question now is, the Z28 came with a oil cooler standard and since my RS is half way to 350, should I put an oil cooler on? Also, should I just go with the a double pass or one with a pusher fan on the front? And what about those sandwich adaptors? Thanks all.

Z28 did not come standard with an oil cooler, it was an available option but was only standard on the showroom stock race cars called G92 or 1LE. Its not nessesary for a daily driver or even a street/strip engine. regardless of displacement.
