Thanks for the tips, I'm looking at the same thing, around 450hp or less, if things go south with my transmission I'll likely be looking at similar upgrades.

Yes it increases line pressure but its only a bandaid. The stocks clutches will still burn up. You obviously don't understand the "modified" C3 pressure plate allows for more clutches for that pack in making it stronger.

i agree a complete rebuild will have no problems. but just putting a shift kit and new TC in an old tranny isnt completely fixing it.
