This is a subject I have some expiernce with. My first suggustion would be not to hook up the
oil cooler. It is not needed, I have one because I thought doing open track events would require one. But they run fine without them (in Florida where the track temp is 110F.
If you insist on hooking it up. Fill the filter with
oil fill the cooler with
oil.
Pull the distributer (mark the timing line with felt marker. Then the location of the roter. Then (and this is the important thing) spin the oil pump counter clockwise. YOu need a special tool for a 302 or 351 they are different. It could be possibe to use an allen wrench socket at the end of an extention but I would hate to loose the socket down deep in the engine.
