beefing up transmission

[Silver R/T]

Its time to rebuild my transmission 727. Ive already got shift kit for it Transgo. What else could I get or have done to it, I want it to handle over 500hp easily and not break apart

I installed a  deep pan with trick billet alum. spacer,premium filter and trick reusable pan gasket from mopar perf.P3690730AB,put on a magnetic drain plug..P4529023AB. 5:1 ratio kickdown lever may be too much.I think the roughly 4:1 ratio is avail. over the counter.I got a premium rebuild kit from Raybestos and there is no junk seals or bands here,just quality.While you're at it throw on a good poly trans mount,
the trans-go kit is great.Have a reputable shop inspect the drum and hub assemby for cracks,and if you are going to throw 5-600 horses at it you might want to put a shield in between your right foot and the alumn case on that 727.I also installed the friction additive for sure-grips in the fluid as i heard it was good for the new clutches,has anyone else used this.I done my tranny in one night and a 6-pack close at hand.amazing it even shifted.Glen
