Time to Beef up the Trans

Hey all, I'm building a 496 for my 66 Monaco right now and am going to need to beef up the stock 727 that rests in the tunnel. It's going to need to withstand around 600 torque and 600 hp I assume.

Do you guys have any rebuild/beef up kits you'd like to reccomend? Should I do a shift kit as well? I've seen Monster is on the site, but wouldnt mind paying less...
