Transmission section for engine swap

I've got a 68 904 that might be in good shape from an old project. Will that transmission work on my 360 without having to beef it up? My swap budget isn't enough to include a beef up of a transmission. Now Ive heard to beef up a 904 I can use certain 727 parts so maybe I could do it that way? Would be free. Is a lockup trans a bad choice for performance? It's better for mileage I understand.
