i was just curious if anybody here has performed a fix for the split engine/trans oil by opening up passages between the eng/trans so that they are like the rfs motor? a race mech i know said some racers are doing this conversion to add more oil quantity. anyone do this? how hard is it? does it help? do you HAVE to split the cases to do it or can you do it by just removing the outter cases? dave h...travis....any other geniuses?
