include a transgo TF-2 shift kit. I'd have to dig out what was recommended to me for the discs/plates etc

I think ht e999 is the one with 5 clutches already in the front pack and 4 in the rear, if so it is the good one. It should have the low 1st and 2nd gear ratios in it also, if not get a set. The low ratio works great and is the strongest factory set of pinions, 4 planatary gears in a steel cage. I would build it with a trans go kit, witch one depends on how hard you want it to shift and if you want it to still shift automatically, I personaly prefer the TF-1 kit with the setting set for max firmness. As for the rest of the trans I like to eliminate the wavy snaprings in the clutch packs, put a spacer in the rear band apply servo to make it solid, put a blocker rod in the middle accumulator to keep it from moveing, make sure you have at least a 3.2 ratio lever up to a 4.2 don't use the 5.0 and filler up with some type-F fluid and it should last a good long time.

Replace the three piece sheetmetal front band with the early style one piece forged band. That's what my 360 used to tear up.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Thanks for all the good infos Dave, my plan was to swap for the sportsman valve body from SMR transmissions.
Next, how do I deal with the lock-up model? if I change valve body, I suppose it won't lock up anymore....so what about the converter ?

It looks to me like the SMR valve body will work with the lock up since they want to make sure it is matched to the year of the trans, I may be wrong but that is the way it apears on there site.
If the VB has lock up elimintated you will still need a LU converter because the input shaft is different, the lock up will just not lock up.

I have used them behind 400+ hp strokers with no problems. The one in my car now has had a turn behind the stock 3182bbl, a 402 stroker, a 318mpg motor and now a stout 360 with ported mag headsXE268 cam M1 single plane intake... and it still shifts great and no broken input The input shaft is hollow but it is bigger diameter so in my opinion it is just as good as the non LU.

It depends on what you want from it. Personally I have an XE268 in the 360 right now and I don't like it. If I had more compression and cubes it would probably be just right for me. I had a custom cam cut for my motor similar to yours and it is a 231 @ .050 .514 lift and I am scared I won't like it. I like a smooth idle and lots of TQ and if it won't go past 6K I could care less.
I can not find an XE286 cam so I am thinking you mean XE268.
If that is the cam you are thinking of useing you should be fine at that compression, the magnum head is very detonaation resistant.
