Gentlemen, I need your expertise. Just pulled my bastardized 48 motor apart. It had knuckle tops. I am putting it back to stock, and have a set of 61 barrels for it. Problem I am having, is gear side case does not have the oil feed holes, nor does it have the oil return hole. The grooves are cut into the left side crank, and yes, the belly numbers match. I thought that maybe the feed and return were welded over and ground, but cant find a trace they were ever there? Also, when I got my gasket kit from James, I got 2 sets of cylinder base gasket, one with feed and return, and a set without. No I'm really f*#@*ed. Any suggestions? Worse case I will drill out the holes and call it a day. Thanks, Tom
