ok, i am rebuilding my 90 and i believe in overkill when it comes to cooling. i bought a new black magic fan and a new all aluminum radiator. i saw this item and was wondering if it can be used as an oil cooler instead of a transmission cooler. only problem is i can't find the specs showing the diameter of the inlets / tubes. i think it can definitely hold up to the internal pressure and heat, so my only concern is restriction of oil flow and dropping my oil pressure - creating a bottleneck in other words. any input?
