I've have the toploader (in a '68 mustang), tko 3550 and the T56 magnum - I don't mind the way the T56 shifts; never really noticed it as a "problem". However, when I had the toploader, I always wanted another gear.

As far as period correct, I think everyone starts out thinking "I want as close to original as possible" but after living with it a while, I started to think, "why compromise? get the transmission and efi to make it more fun to drive everyday; that extra gear doesn't impact the originality more than the pleasure I get from having those extra gears"
