what makes an ultimate sprag better?
It has more rollers and springs and makes it virtually impossible for the rollers to roll over , the rollers are a little smaller in size but there are more of them .

is this a street car , race car , autio VB or manual ?
It's a Race Car 9.80's Hemi Coronet. We really don't want to get into drilling the case for the bolt in. The guy doing our Transmission said the Sprag looked good, I just felt that while we have it apart we might as well put a new one in. If changing the Springs and Rollers will help than thats is an idea.
Thanks

You realy should go with the bolt in. Do a srarch in mopar action I belive and see what happens when a 727 lets go it's like a bomb going off under the car when the sprag takes a dump and it will sooner or later. You see it's not a question of will it go away it will, it's when, and for that thing it's always the wrong time. Always take the side of safty bolt in is the only way to go. JoWeTu_6

KEVIN,i just took my 727 apart,my aluminum drum was worn alittle, i am replacing my drum with a billet steel one and while my drum is apart i am changing to a BOLT IN SPRAG, for $175.00 its a no brainer.
without a bolt in sprag, its a matter of time before that tranny lets loose and goes through your floor cutting off dads leg.
with the power you making now, you have to really upgrade your parts correctly to avoid an accident that can be prevented, build it right the 1st time, it will save you money and aggravation later on.

We usually only replace the springs and rollers,about $25.We do use the bolt in overrunning clutch if there is damage to the the inner or outer support rings.The bolts that hold the clutch(sprag) in place do nothing to stop the it from "exploding" If it is going to happen(usually from abuse or incorrect use or other drive line breakage)
FINALLY!!! A voice of reason!

 this is absolutly correct and for info the ultimate sprag from Coan uses the 4 holes in the case with nice shoulder bolts.
The only problem with the one that Coan uses is the shouldered bolt is necked down to a 1/4 thread and fastener and the srings and rollers are so small that I always find broken springs and flat rollers.I still preferr the stock style large springs and rollers.

Since it's a drag car I wouldn't change out the orignal unless it's damaged , if you want to change it anyway use the A+A. You don't really need to drill for the 2 extra bolts, later 727's have a 6 bolt rear support in that case you don't have to do much drilling if that's the case you have. BUT if you just change the springs and rollers buy the A+A billet drum, or go with an Alum drum, either way if the srag fails you won't end up with the trans coming thru the floor .

If you don't have a billet drum in it now get one.
Don't let this happen to you.
