I'm having trouble finding geometry specs on any of the Centurion Ironman bikes. I'm riding a 1986 Centurion Dave Scott Ironman right now (not the Expert or Master). I can't really tell the differences from my Schwinn Prologue frame, which has 74.5 ST and 73 HT angles (both frames are 56cm) qualitatively, but I would guess that the Centurion has a more relaxed seat tube angle. Here's a link to some pictures and specs for reference:

FYI, the serial # is KG511572.
I'm going to take all those "vintage parts" off the Centurion and swap them with the "race parts" on my Schwinn since the frame is damaged and I want something reliable to train on. (Alas, the Schwinn will be confined to campus bike duties...)
I may try to get one of those angle measuring ruler things and just measure manually...
EDIT: I guess there was not an actual question (with a "?") when I wrote this, but here it is: What is the geometry of this Centurion frame?
