A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)

in all my years of doing torqueflites, i have never seen sprag failure due to lack of lube. i have seen lots of inner races cut into the case though. for those we machine the case for a bearing. i got curious and went to the shop cause i have one apart. measured 3/4" in from the bore and that put the hole right under the roller spring. so when oil comes out of that hole, it would shoot through the spring and hit the backside of the drum. centrifical force may carry the oil around and flood the sprag. at best it willl splash all over. ok, but that still doesnt put oil behind the race where its needed. this mod maybe ok for a drag only car. do you realize how much oil comes out of a 1/8 hole at 40-60 psi? its wasted lube. i would rather it go to the planetarys and every thing else hanging off the mainshaft. on the next one you want to do, turn the reverse drum upside down and put the race on it. you will notice that race sits a bit higher than the drum giving a little pocket. if you were to drill a .040 hole about 6mm in from the case bore, it would pressurize this pocket and force the oil under the race where its needed.
