If your going to stay with the 727, id talk to COPE,
Saying you would never put a t400 in there.....You just don't realize what parts are available and whats really better to handle the power.
I talked to Cope and Rossler when I had enough of broken trans and parts...Cheaper in the long run to put a GOOD unit in there that will handle all that you can put in front of it

....BAD A$$ STREET CAR.....
