That actually is something I do need and have put a lot of thought into Randy. Sermis just put hose barbs on his block and ran 3/8" hose to a transmission cooler in front of his radiator when he put a 6.2 in his M715. It works.

However, I keep thinking about why GM went to the trouble of making aluminum lines go all the way across the radiator in front of the fan and then plug into the cooler. There must be a need for more cooling than just a cooler can provide.

I have enough room in front of my 28" Summit aluminum radiator to put a condensor for my anticipated a/c set up and probably a really cleaned out condensor used as the oil cooler or a pair of transmission coolers. Either way, I will have to finally get around to building a fan shroud and I will use the biggest brake line I can get to hook into custom built hydraulic hoses to carry the oil from the engine to the front.

I am actually thinking about a Mazda RX-7 aluminum oil cooler. They have a thermostat in them that works just like a coolant thermostat so the oil won't get too cold in the winter. The problem with that is pipe fittings on the block and metric at the cooler. Even though the 6.2 is a metric block, I want to keep this truck as simple as possible to work on while out and about. Mixing fittings between standard and metric is not something I want.
