Re: blown 460
A manual behind a blown 460?? Geeez, yuck!!!
Always been a fan of the 2-speed Power-Glide for blown big blocks. With that much torque, you only need 2 gears mate. Put a manual behind it and you'll be forever stuffing around with clutches.
As for internals, you've got two options: Cheap and unreliable, or built properly for many $$$$
