What's up Dude,
Thanks for the kind words. If you tripped over that 4L80E and dug it out of the dirt, it should handle 500HP. You didn't specify engine output, so I'm not sure what mods to recommend. A performance rebuild IS a good idea since you get heavy duty bands, clutches and such. But if the doner vehicle was in good shape, feel free to wear it out and then do a major rebuild. A shift kit is recomended since it build mechanical line pressure. Then you will be able to fine tune the pressure curves with a computer.
Spring swap? It ain't THAT heavy. So no. Just heavy-er. Reply with engine specs and maybe I can be more helpful.________________
