A904 high performance rebuild--advice wanted

UPDATE:

OK... dropped off the transmission last week. The shop had lots of high performance stuff around, seemed to be living up to their reputation as a hot rod transmission shop. The guys seemed to know their stuff though they had doubts about the A904....despite my insistance that I wasn't "reinventing the wheel."

They said they would call me back by the end of the week after they had a chance to check out the condition, then they would give me a quote on the build and I would give them the specific components that I was looking for.

I never heard back so I called this morning...they said the transmission was ready to pick up! GRRR!! What? Basically, they did a standard rebuild with a mild shift kit.

I said that this wasn't what I had in mind and I was never given a chance to talk specific components (as you guys mentioned above).... he admitted the mistake and said that it was no problem, they would take it apart and do whatever I was looking for....but he was pretty sure that it would hold up. :rolleyes:

In the case that this WOULD hold up, it would be a great thing since I'm at 50% of my rebuild budget.

So my question is this- what would happen if I ran the transmission as-is? Would it slip? Would it burn up? The crate motor will only be putting out 300ish hp this year but I'd like to start modding and adding power in the near future. I'd like to take it to the strip a few times this summer...

Thanks for any additional advice, guys...

To answer your specfic question, no it won't slip or burn up just because it doesn't have high performance parts in it.
Since you are concerned about budget, just run it and spend the money on the recommended converter.

What's a "mild" shift kit? (This will make a pretty big difference)
If it's not at least a TF2 or equivelent, then have them do that and let it go.
That and an external cooler should get you through multiple racing seasons.
